The right ducting to create safe and efficient environment in the food and pharmaceutical industry

Dust extraction and process ventilation are critically important in both the food waste environments and pharmaceutical industries because airborne particles pose serious risks to product safety, worker health, and regulatory compliance.

In food-waste environments, cross‑contamination, mould growth, pathogen spread, and compromised hygiene standards are the main risks of poor dust extraction systems. Effective process ventilation helps prevent airborne contamination, reduces the spread of dust, allergens, and microbes, and supports compliance with strict hygiene regulations.

In the pharmaceutical sector, manufacturing processes involving powders and active pharmaceutical ingredients (APIs) generate hazardous fine dusts that can endanger workers, interfere with machinery, and cause cross‑contamination between drug batches. Robust dust extraction and suitable ducting systems are therefore essential to protect employee health, maintain cleanroom classifications, and meet stringent GMP and regulatory standards. Together, these systems ensure cleaner air, safer work environments, and consistent product quality in two of the world’s most tightly regulated industries.

Critical dust extraction points in the food and pharmaceutical industry:

Ingredient handling & raw material dispensing release airborne dust when powders or dried organic materials are scooped, poured, dosed, or weighed.
Mixing, blending & agitation processes liberates fine particulates, whether from decomposed food waste or active pharmaceutical ingredients (APIs).
Conveying, chutes & material transfer systems produces dust as material flows, drops, or changes direction.
Milling, grinding, crushing or size‑reduction equipment generate high volumes of fine dust, requiring strong extraction to avoid contamination and hazards.
Cleaning, sieving & screening operations disturb settled dust and generate airborne particulates, making these shared high‑risk points.

Why dust collection matters in food waste applications

Australian standards such as AS/NZS 1715, AS 4674, and Safe Work Australia guidelines mandate strict control of airborne contaminants in food facilities to protect both workers and consumers. Without proper dust collection handling, dust from food processing and waste handling can:

Compromise air quality, leading to respiratory risks for workers.
Contaminate products, affecting safety and quality.
Create fire and explosion hazards, especially with combustible organic dust.
Attract pests, increasing sanitation risks.
Violate environmental and workplace safety regulations.

Ready to upgrade your dust collection system?

Whether you're retrofitting an existing plant or designing a new waste handling line, our team can help you build a compliant, efficient, and hygienic solution, including our laser-welded Nordfab HygiDuct ducting system. Our standard ducting components range from 76 - 400 mm in diameter, clamped together with our perfectly round food grade high vacuum style clamp.

Powerful, energy-efficient dust collection for safer workplaces and cleaner production environments

The Nordfab MDC Dust Collector Range delivers reliable, high-efficiency dust extraction for demanding industrial environments. Designed for continuous operation, MDC systems help improve workplace air quality, support compliance with WHS/OHS requirements, and maintain safe, productive facilities.

With modular, scalable designs and airflow capacities from 4,000 to 250,000 m³/h, MDC collectors can be tailored to everything from individual machines to large centralised dust collection systems. Advanced PLC controls, efficient filter cleaning, and optional Variable Speed Drive (VSD) technology help optimise performance while reducing energy consumption and maintenance costs.

Built for durability and consistent performance, MDC dust collectors are ideal for woodworking, metalworking, recycling, food processing, pharmaceuticals, and other industrial applications. Backed by local Australian engineering support, they provide a dependable, future-ready solution for effective dust control and cleaner operations.

Selecting appropriate ducting

In food waste environments, ducting must be engineered for uncompromising hygiene, safety, and regulatory compliance. Organic dust from processing and waste handling can quickly accumulate inside poorly designed duct systems, leading to contamination risks, microbial growth, and odours that compromise sanitation standards.

HygiDuct product range

The fully laser-welded ducting system, Nordfab HygiDuct, is purpose-built for the demanding conditions of food-waste environments. Engineered to handle the challenges of organic dust, heavy contamination loads, and frequent high-pressure washdown, Nordfab HygiDuct delivers exceptional hygiene and durability. Its ultra-smooth, crevice-free interior prevents material build-up and significantly reduces the risk of contamination, microbial growth, and unwanted odours—helping facilities maintain cleaner, safer, and more compliant operations.

Superior Hygiene: Smooth, fully laser-welded seams prevent dust buildup and eliminate bacterial growth.
Leak-Tight Performance: Its laser-welded seams offer airtight integrity, reducing emissions and improving system efficiency. The Nordfab HygiDuct is engineered for durability and performance, the ducting components feature robust standard 1.2 mm wall thickness and raw ends for seamless integration, secured with high vacuum, food-grade clamps that ensure a tight, hygienic seal.
Corrosion Resistance: Nordfab HygiDuct is available in 316SS, resisting acids, moisture, and harsh cleaning agents - ideal for food waste and organic dust environments.
Modular & Scalable: Nordfab HygiDuct is easily adaptable to new layouts or expansions as the components are available as straight ducts, bends, branches, reducers, and clamps - everything
needed to build a robust ducting system.
