WhatFour duties bought as one system

Industrial ventilation covers four distinct duties that are often bought together: general dilution ventilation to keep the whole workspace within exposure limits, local exhaust to capture a contaminant at its source, process air supplied to equipment, and heat removal from hot processes. Each has a different design basis, and mixing them up is the most common cause of a system that cost a lot and did not work.

WhoWho specifies industrial ventilation

Plant and facilities engineers, EPC contractors, ventilation system integrators, and specialist operators in foundries, metal finishing, paint and coating lines, chemical processing, grain handling and mining.

WhereWhere explosion protection is mandatory

Every manufacturing region, with specification driven by whichever occupational exposure regime applies locally. Where solvent vapour, combustible dust or flammable gas can be present, explosion-protected construction is a legal requirement rather than an option — 80 products on this site carry that rating.

WhenLine changes and hygiene audits

At plant construction, when a production line changes and the extraction no longer matches what it is meant to capture, and after an occupational hygiene or safety audit that has found exposure above limits. The last of these usually comes with a compliance deadline attached.

WhyThe system curve decides everything

Fan selection lives or dies on the system curve, and this is where most industrial ventilation money is wasted. A fan quoted at a free-air airflow figure will deliver a fraction of that once ductwork, bends, filters and a discharge stack have added static pressure — and the buyer discovers this only after installation, when the hood no longer captures. The correct comparison is always airflow at the system's design static pressure, from the fan's published curve.

HowMatching fan type to pressure regime

Establish two numbers before looking at any product: the required volume flow, and the static pressure the system will impose at that flow. Then match the fan type to the pressure regime — axial fans for high volume at low pressure, backward-curved centrifugal for medium to high pressure at good efficiency, and radial or paddle-blade impellers where the air carries dust or fibre that would clog a curved blade. Add the environmental requirements last: explosion protection, high-temperature construction, or corrosion-resistant materials.

Equipment this application needs

Axial Flow Fans High volume, low pressure Axial Flow Fans666 General dilution ventilation, roof and wall extract, and cooling airflow where there is little ductwork to fight. Centrifugal Fans Medium to high pressure Centrifugal Fans293 Ducted extraction and process air. Backward-curved impellers give the best efficiency and a non-overloading power characteristic. Radial Fans Dust-laden air Radial Fans194 Straight radial blades that pass particulate without building up deposits — the right choice for woodworking, grain and foundry extraction. Blowers Process & conveying air Blowers212 Higher pressure at lower volume: pneumatic conveying, combustion air, aeration and drying. Industrial Fans Workshop cooling Industrial Fans73 Floor and wall-mounted air movement for worker comfort in hot plant areas. Cooling Towers Process heat rejection Cooling Towers135 Rejecting heat from process cooling water, sized on wet-bulb rather than dry-bulb temperature.

What to check before you order

Explosion Proof 80
Mandatory wherever a flammable atmosphere can occur. Covers motor, bearings and impeller material, not just the motor.
High Temperature 113
Kiln, oven, foundry and furnace extraction where the air itself is hot.
Corrosion Resistant 103
Plating, pickling and chemical process extraction — the duct contents attack the fan continuously.
Industrial Grade 573
Continuous duty construction with serviceable bearings and standard replaceable motors.
380V 751
Three-phase supply, standard for anything above fractional horsepower.

Questions buyers ask

How do I choose between an axial, centrifugal and radial fan?
By the pressure the system imposes and by what is in the air. Axial fans move large volumes efficiently when resistance is low — short duct runs, wall and roof extract. Backward-curved centrifugal fans hold their volume as resistance rises, which makes them right for ducted systems with filters and bends. Radial or paddle-blade impellers are less efficient but their straight blades will not accumulate dust, so they handle particulate-laden air that would progressively unbalance a curved impeller.
Why does my new fan move less air than its rating?
Almost certainly because the rating was free-air airflow and your system has static pressure. Every metre of duct, every bend, every filter and the discharge stack itself all add resistance, and the fan moves down its own performance curve as a result. The number to compare when buying is airflow at the design static pressure, taken from the fan curve — not the headline figure.
When is an explosion-proof fan legally required?
Whenever a flammable or explosive atmosphere may be present in the airstream or around the fan — solvent vapour from paints and coatings, combustible dust from wood, grain or metal, or flammable process gas. The requirement covers the whole assembly: motor certification, non-sparking impeller and housing materials, and bearing protection. Local classification of the zone determines the required category, so classify the zone before selecting the fan.
