In a food processing plant, a fan is not simply a mechanical component. It is a piece of equipment continuously exposed to conditions found in very few industrial environments: persistent humidity, fatty vapors laden with organic acids, repeated thermal shocks between cold and hot zones, and aggressive cleaning with chlorinated or peracetic acid disinfectants. In this context, standard metal fans prove quickly unsuitable — and the consequences reach far beyond a simple breakdown.
Metal fans: a risky choice in food environments
Galvanized steel or aluminum, even when surface-treated, cannot withstand daily cleaning with alkaline or disinfectant products over time. Corrosion sets in progressively: invisible at first, it eventually contaminates the air stream, compromises installation integrity, and causes unplanned production stoppages. In process or packaging areas, this is simply not acceptable.
Hygiene compliance is also at stake. A fan that degrades sheds particles — paint flakes, metallic debris — that can constitute a physical contamination risk. IFS, BRC, and ISO 22000 audits are increasingly stringent on this point.
Thermoplastic: the technical answer to these constraints
Fans made from thermoplastic materials (polypropylene) offer intrinsic chemical resistance that surface treatments cannot match over time. There is no coating to maintain, no risk of flaking, no degradation from standard cleaning products used in the food industry.
The practical advantages are clear:
- Permanent chemical resistance to organic acids, alkaline solutions, and common disinfectants
- Lightweight construction simplifying installation and maintenance
- Smooth surfaces minimizing bacterial retention zones
- Extended service life in humid or corrosive environments, with no corrective intervention required
This is precisely why SEAT fans — designed and assembled in France for over 55 years — are installed in cutting rooms, modified atmosphere packaging units, cooking areas, and washdown zones.
Ventilation as a regulatory compliance lever
Beyond material durability, ventilation plays a direct role in food site compliance. EC Regulation 852/2004 on the hygiene of foodstuffs requires operators to have adequate ventilation systems to prevent condensation build-up and control air quality in production areas. The IFS Food and BRC Global Standard for Food Safety align with this, with explicit requirements on the control of airborne contamination.
This calls for equipment capable of handling air flows laden with vapors or odors, without generating secondary risks. A fan that withstands the environment and is easy to inspect is also a fan that passes audits.
EC Regulation 852/2004 — Hygiene of foodstuffs: ventilation systems must be designed to prevent condensation and control air quality in production areas.
IFS Food & BRC Global Standards: explicit requirements on the control of airborne contamination and the cleanability of equipment.
What SEAT Ventilation delivers in practice
SEAT's food industry offering is built around corrosion-resistant fan ranges sized for the flow rates and static pressures typical of the sector. Depending on the application — cooking vapor extraction, gaseous effluent treatment, general ventilation of refrigerated halls — the SEAT, STORM, and JET series cover the full range of requirements.
SEAT Series
General extraction and gaseous effluent handling in humid and corrosive environments.
STORM Series
High static pressure for complex duct networks and long-distance installations.
JET Series
Compact and versatile for space-constrained installations.
French manufacturing
Controlled lead times and long-term spare parts availability — two critical factors for continuous production sites.
