When ducts are poorly designed or installed, cooling and ventilation performance drops sharply — compressors work harder, electricity bills climb, and production floor operator comfort suffers.\u003C/p>\n\n\u003Cp>Many factory managers and contractors overlook duct material selection, assuming all ductwork is interchangeable. In reality, the wrong material can cause up to 30% air leakage, premature corrosion, and a severely shortened service life. In food and pharmaceutical sectors, non-hygienic ducting can even trigger audit findings and certification rejections.\u003C/p>\n\n\u003Cp>This guide covers everything you need to know about selecting the right HVAC duct material for factory environments, plus correct installation methods to ensure optimal ventilation performance and long-term durability.\u003C/p>\n\n\u003Ch2>Types of HVAC Ducting Materials for Factories\u003C/h2>\n\n\u003Cp>Material selection depends on industry type, operating temperature, air pressure, and cleanliness requirements. Here are the four primary materials used in Indonesia's industrial sector:\u003C/p>\n\n\u003Cimg src=\"https://assets.sandwichpanels.id/blog/1783045106347-20260703-021826-hvac-ducting-diagram-01.jpg\" alt=\"Cross-section diagram of industrial HVAC ducting system with insulation layers\" style=\"max-width:100%;height:auto;margin:16px 0;border-radius:8px;\" />\n\n\u003Ch3>1. Galvanized Steel (BJLS) Duct\u003C/h3>\n\n\u003Cp>The most common ducting material for general factories. Zinc coating on carbon steel provides corrosion resistance at an affordable price point. Suitable for general manufacturing plants, warehouses, and standard production areas. Available in thicknesses from 0.5 mm to 1.2 mm per ASHRAE standards.\u003C/p>\n\n\u003Cp>The main drawback: limited lifespan in high-humidity or chemical-exposure environments. In food processing facilities with wet washdown areas, galvanized steel can begin rusting within 2-3 years.\u003C/p>\n\n\u003Ch3>2. Stainless Steel Duct\u003C/h3>\n\n\u003Cp>Stainless steel ducting (SS304 or SS316) is mandatory for pharmaceutical, food and beverage, and cleanroom facilities implementing GMP and HACCP standards. The smooth, non-porous surface prevents dust accumulation and microbial growth while resisting CIP (Clean-in-Place) processes.\u003C/p>\n\n\u003Cp>Stainless steel costs 3-4 times more than galvanized steel, but its service life reaches 15-20 years with minimal maintenance. For ISO Class 5-8 cleanrooms, stainless steel ductwork is the de facto standard.\u003C/p>\n\n\u003Ch3>3. Aluminium Duct\u003C/h3>\n\n\u003Cp>Sixty percent lighter than steel, aluminium is ideal for installations in tight-access areas or buildings with structural load limitations. It offers natural corrosion resistance without additional coatings. Commonly used for exhaust ducts and fresh air intakes in electronics factories and server rooms.\u003C/p>\n\n\u003Cp>Drawbacks: lower mechanical strength, unsuitable for high-pressure ducting, and prone to denting during handling and installation.\u003C/p>\n\n\u003Ch3>4. PIR Sandwich Panel Duct — Integrated Insulation\u003C/h3>\n\n\u003Cp>For cold storage and climate-controlled cleanroom applications, PIR (Polyisocyanurate) panels with metal skins double as pre-insulated air ducts. No additional insulation wrapping is needed, saving space and installation time. With extremely low thermal conductivity (0.022 W/m·K), PIR ducts maintain stable internal air temperatures.\u003C/p>\n\n\u003Cp>PIR panels also achieve fire ratings up to B1 (class 0 BS476) and are CFC/HCFC-free, meeting international environmental and fire safety standards.\u003C/p>\n\n\u003Ch2>Common Causes of Factory Ducting Problems\u003C/h2>\n\n\u003Cp>Before diving into installation guidelines, understand the root causes of recurring issues:\u003C/p>\n\n\u003Cul>\n\u003Cli>\u003Cstrong>Undersized ducts:\u003C/strong> Excessive air velocity, noise levels above 45 dBA, and high pressure drop overloading the fan.\u003C/li>\n\u003Cli>\u003Cstrong>Joint leakage:\u003C/strong> Improper sealant or loose flange connections causing 15-30% air leakage. Every 10% leakage equals 5-8% wasted energy.\u003C/li>\n\u003Cli>\u003Cstrong>Inadequate insulation:\u003C/strong> Without proper insulation, cold air inside the duct condenses on the outer surface, causing dripping water and potential mold growth.\u003C/li>\n\u003Cli>\u003Cstrong>Insufficient support brackets:\u003C/strong> Excessive support spacing causes duct sagging, disrupting airflow patterns and stressing connections.\u003C/li>\n\u003Cli>\u003Cstrong>Wrong material for environment:\u003C/strong> Galvanized steel used in wet areas, or stainless steel wasted on non-critical exhaust (cost overrun).\u003C/li>\n\u003C/ul>\n\n\u003Ch2>Recommended Products for Factory HVAC Ducting\u003C/h2>\n\n\u003Cp>Based on factory type and requirements, here are material recommendations from SandwichPanels.id:\u003C/p>\n\n\u003Cul>\n\u003Cli>\u003Cstrong>General factories & warehouses:\u003C/strong> Galvanized steel duct + 25-50 mm glasswool insulation\u003C/li>\n\u003Cli>\u003Cstrong>Food & beverage plants:\u003C/strong> SS304 stainless steel duct, welded joints, pitched toward drain\u003C/li>\n\u003Cli>\u003Cstrong>Pharmaceutical & cleanroom facilities:\u003C/strong> SS316L stainless steel + PIR panel duct for ISO Class 5-7 areas\u003C/li>\n\u003Cli>\u003Cstrong>Electronics factories:\u003C/strong> Aluminium duct for fresh air + stainless steel for exhaust\u003C/li>\n\u003Cli>\u003Cstrong>Cold storage & freezers:\u003C/strong> PIR sandwich panel duct at 75-150 mm thickness\u003C/li>\n\u003Cli>\u003Ca href=\"https://sandwichpanels.id/en/artikel/sistem-ventilasi-pabrik-solusi-sandwich-panel-2026\">Factory Ventilation: Sandwich Panel & HVAC Solutions\u003C/a> — Read more about factory ventilation.\u003C/li>\n\u003Cli>\u003Ca href=\"https://sandwichpanels.id/en/artikel/panel-sandwich-adalah-pengertian-jenis-keunggulan-2026\">What Are Sandwich Panels?

Using it for main runs creates 3x the pressure drop of rigid duct.\u003C/li>\n\u003Cli>\u003Cstrong>No access doors:\u003C/strong> Long duct runs without inspection access make cleaning and maintenance difficult. Install access doors every 6-8 meters.\u003C/li>\n\u003Cli>\u003Cstrong>Imperfect welding:\u003C/strong> For stainless ductwork, rough or uneven weld beads become particle and microbe collection points in cleanroom environments.\u003C/li>\n\u003C/ol>\n\n\u003Ch2>FAQ: Factory HVAC Ducting Installation\u003C/h2>\n\n\u003Ch3>What is the minimum thickness standard for galvanized steel factory ducting?\u003C/h3>\n\u003Cp>Per SMACNA (Sheet Metal and Air Conditioning Contractors' National Association) standards: for rectangular ducts with the longest side 300-750 mm, minimum thickness is 0.6 mm (gauge 24). For sides 750-1500 mm, minimum 0.8 mm (gauge 22). Above 1500 mm, use 1.0 mm or add reinforcement.\u003C/p>\n\n\u003Ch3>What does HVAC ducting installation cost per meter?\u003C/h3>\n\u003Cp>Costs vary significantly based on material and complexity. Rough estimates: galvanized steel duct IDR 350,000-600,000/m² (material + installation), stainless steel IDR 1,200,000-2,000,000/m², PIR panel duct IDR 800,000-1,500,000/m². Prices exclude insulation, supports, dampers, and diffusers.\u003C/p>\n\n\u003Ch3>Is HVAC ducting insulation mandatory?\u003C/h3>\n\u003Cp>Yes, for ducts carrying cold air (supply air), insulation is essential to prevent condensation and maintain thermal efficiency. Minimum 25 mm glasswool insulation at 24-32 kg/m³ density for standard AC ductwork. For cold storage (-18°C), use 75-100 mm PIR insulation.\u003C/p>\n\n\u003Ch3>How do you test duct leakage after installation?\u003C/h3>\n\u003Cp>Use a duct leakage test per SMACNA standards. Pressurize the duct to 250-500 Pa and measure leakage rate. For Class A (general) ductwork, the maximum allowable leakage is 0.027 L/s per m² of duct surface area at 250 Pa test pressure.\u003C/p>\n\n\u003Ch3>What is the service life of factory HVAC ducting?\u003C/h3>\n\u003Cp>Galvanized steel duct with proper insulation: 10-15 years. Stainless steel: 20-25 years. PIR panel duct: 15-20 years. Factors reducing lifespan: high humidity, chemical exposure, machinery vibration, poor maintenance, and substandard initial installation.\u003C/p>\n\n\u003Ch2>Conclusion\u003C/h2>\n\n\u003Cp>Proper HVAC ducting installation starts with selecting the right material for your industry and factory environment. Don't be tempted by the cheapest option — calculate total cost of ownership including energy, maintenance, and service life. Ducting designed and installed to SMACNA standards saves 15-25% on energy costs and lasts twice as long as haphazard installations.\u003C/p>\n\n\u003Cp>Consult our technical team for your factory's HVAC ducting requirements.

Tanpa saluran yang dirancang dan dipasang dengan benar, performa pendinginan dan ventilasi akan menurun drastis — AC bekerja lebih keras, tagihan listrik naik, dan kenyamanan operator produksi terganggu.\u003C/p>\n\n\u003Cp>Banyak manajer pabrik dan kontraktor mengabaikan pemilihan material ducting, menganggap semua ducting sama saja. Padahal, material yang salah bisa menyebabkan kebocoran udara hingga 30%, korosi dini, dan umur pakai ducting yang pendek. Di sektor pangan dan farmasi, material ducting yang tidak higienis bahkan bisa berujung pada temuan audit dan penolakan sertifikasi.\u003C/p>\n\n\u003Cp>Artikel ini membahas panduan lengkap memilih material ducting HVAC yang tepat untuk lingkungan pabrik, plus cara pemasangan yang benar agar sistem ventilasi bekerja optimal dan tahan lama.\u003C/p>\n\n\u003Ch2>Jenis Material Ducting HVAC untuk Pabrik\u003C/h2>\n\n\u003Cp>Pemilihan material ducting bergantung pada jenis industri, suhu operasi, tekanan udara, dan persyaratan kebersihan. Berikut empat material utama yang umum digunakan di sektor industri Indonesia:\u003C/p>\n\n\u003Cimg src=\"https://assets.sandwichpanels.id/blog/1783045106347-20260703-021826-hvac-ducting-diagram-01.jpg\" alt=\"Diagram potongan sistem ducting HVAC industri dengan lapisan insulasi\" style=\"max-width:100%;height:auto;margin:16px 0;border-radius:8px;\" />\n\n\u003Ch3>1. BJLS (Baja Lapis Seng) — Galvanized Steel Duct\u003C/h3>\n\n\u003Cp>Material paling umum untuk ducting pabrik. Lapisan seng (zinc) pada baja karbon memberikan ketahanan terhadap karat dengan harga terjangkau. Cocok untuk pabrik umum, gudang, dan area produksi standar. Tersedia dalam ketebalan 0,5 mm hingga 1,2 mm sesuai standar ASHRAE.\u003C/p>\n\n\u003Cp>Kelemahan utama BJLS adalah umurnya terbatas di lingkungan dengan kelembaban tinggi atau paparan bahan kimia. Di pabrik pengolahan makanan dengan proses pencucian basah, BJLS bisa mulai berkarat dalam 2-3 tahun.\u003C/p>\n\n\u003Ch3>2. Stainless Steel Duct — Baja Tahan Karat\u003C/h3>\n\n\u003Cp>Ducting stainless steel (SS304 atau SS316) wajib digunakan di pabrik farmasi, makanan, minuman, dan cleanroom yang menerapkan GMP dan HACCP. Permukaan yang halus dan non-porous mencegah penumpukan debu dan pertumbuhan mikroba, sekaligus tahan terhadap proses CIP (Clean-in-Place).\u003C/p>\n\n\u003Cp>Biaya stainless steel 3-4 kali lebih mahal dibanding BJLS, namun umur pakainya bisa mencapai 15-20 tahun dengan perawatan minimal. Untuk ruang bersih ISO Class 5-8, ducting stainless adalah standar de facto.\u003C/p>\n\n\u003Ch3>3. Aluminium Duct\u003C/h3>\n\n\u003Cp>Lebih ringan 60% dibanding baja, aluminium cocok untuk instalasi di area dengan akses terbatas atau bangunan dengan keterbatasan beban struktur. Tahan korosi alami tanpa perlu pelapisan tambahan. Sering digunakan untuk exhaust duct dan fresh air intake di pabrik elektronik dan ruang server.\u003C/p>\n\n\u003Cp>Kekurangannya: kekuatan mekanis lebih rendah, tidak cocok untuk ducting bertekanan tinggi, dan rentan penyok saat handling atau instalasi yang kurang hati-hati.\u003C/p>\n\n\u003Ch3>4. PIR Sandwich Panel Duct — Insulasi Terpadu\u003C/h3>\n\n\u003Cp>Untuk aplikasi cold storage dan cleanroom berpendingin, panel PIR (Polyisocyanurate) dengan lapisan metal skin sekaligus berfungsi sebagai dinding saluran udara berinsulasi. Tidak perlu wrapping insulasi tambahan, menghemat ruang dan waktu instalasi. Nilai konduktivitas termal sangat rendah (0,022 W/m·K), menjaga suhu udara dalam duct tetap stabil.\u003C/p>\n\n\u003Cp>Panel PIR juga memiliki fire rating hingga B1 (class 0 BS476) dan bebas CFC/HCFC, memenuhi standar lingkungan dan keselamatan kebakaran internasional.\u003C/p>\n\n\u003Ch2>Penyebab Masalah Ducting di Pabrik\u003C/h2>\n\n\u003Cp>Sebelum masuk ke panduan pemasangan, penting memahami akar masalah yang sering muncul:\u003C/p>\n\n\u003Cul>\n\u003Cli>\u003Cstrong>Ukuran duct terlalu kecil:\u003C/strong> Menyebabkan kecepatan udara berlebih, suara bising (>45 dBA), dan pressure drop tinggi yang membebani fan.\u003C/li>\n\u003Cli>\u003Cstrong>Sambungan bocor:\u003C/strong> Sealant yang tidak tepat atau sambungan flange yang longgar menyebabkan kebocoran udara 15-30%.

Untuk sisi >750-1500 mm, minimum 0,8 mm (gauge 22). Di atas 1500 mm, gunakan 1,0 mm atau reinforcement tambahan.\u003C/p>\n\n\u003Ch3>Berapa biaya instalasi ducting HVAC per meter?\u003C/h3>\n\u003Cp>Biaya sangat bervariasi tergantung material dan kompleksitas. Estimasi kasar: BJLS duct Rp 350.000-600.000/m² (termasuk material + instalasi), stainless steel Rp 1.200.000-2.000.000/m², PIR panel duct Rp 800.000-1.500.000/m². Harga belum termasuk insulasi, support, damper, dan diffuser.\u003C/p>\n\n\u003Ch3>Apakah ducting HVAC wajib diinsulasi?\u003C/h3>\n\u003Cp>Ya, untuk ducting yang membawa udara dingin (supply air), insulasi wajib untuk mencegah kondensasi dan menjaga efisiensi termal. Ketebalan insulasi minimum 25 mm glasswool dengan density 24-32 kg/m³ untuk ducting AC standar. Untuk cold storage (-18°C), gunakan insulasi PIR 75-100 mm.\u003C/p>\n\n\u003Ch3>Bagaimana cara menguji kebocoran ducting setelah instalasi?\u003C/h3>\n\u003Cp>Gunakan duct leakage test sesuai standar SMACNA. Tekan duct dengan tekanan 250-500 Pa dan ukur laju kebocoran. Untuk ducting kelas A (umum), kebocoran maksimal yang diizinkan adalah 0,027 L/s per m² luas permukaan duct pada tekanan uji 250 Pa.\u003C/p>\n\n\u003Ch3>Berapa umur pakai ducting HVAC pabrik?\u003C/h3>\n\u003Cp>Ducting BJLS dengan insulasi baik: 10-15 tahun. Stainless steel: 20-25 tahun. PIR panel duct: 15-20 tahun. Faktor yang memperpendek umur: kelembaban tinggi, paparan kimia, getaran mesin, kurang maintenance, dan instalasi awal yang buruk.\u003C/p>\n\n\u003Ch2>Kesimpulan\u003C/h2>\n\n\u003Cp>Instalasi ducting HVAC yang tepat dimulai dari pemilihan material yang sesuai dengan jenis industri dan lingkungan pabrik Anda.
