Fans & Blowers

100 catalogues

Centrifugal, axial, mixed-flow, duct, cross-flow and special-purpose fans and blowers for HVAC, refrigeration, industrial and appliance OEMs.

Centrifugal Fans 35

Centrifugal fans turn air through 90° and build higher static pressure than axial fans, so they suit ducted systems, AHUs, filters and process air.

Axial Fans 14

Axial fans move large air volumes at low pressure — for condensers, cooling, wall exhaust, tunnels and general ventilation.

Mixed-Flow Fans 1

Mixed-flow fans combine axial and centrifugal flow for higher pressure than axial fans in a compact inline form.

Inline Duct Fans 27

Inline fans installed directly in round or rectangular ducts for residential, commercial and light-industrial ventilation.

Cross-Flow & Tangential Fans 7

Cross-flow (tangential) fans deliver an even, wide air stream for air curtains, split ACs, heaters and equipment cooling.

Regenerative Side-Channel Blowers 1

Regenerative blowers deliver vacuum or pressure for aeration, conveying, packaging and printing machinery.

Special-Purpose Blowers 10

Blowers for gas burners, inflatables, floor drying, handheld use and Roots-type duties.

Air Circulators & Portable Air Movers 7

HVLS ceiling fans, drum fans, misting fans and portable ventilators for factories, warehouses, farms and confined spaces.

Motors & Drives

24 catalogues

AC induction, EC, BLDC and permanent-magnet motors, plus speed controllers for fan and appliance OEMs.
