Secomak 575/4 High Velocity Blower
A belt-driven high velocity blower giving up to 250 m³/h and 52 mbar on a 0.55 kW single or three phase motor. For drying, blow-off, and process air where pressure matters.
At a glance: The Secomak 575/4 is a belt-driven high velocity blower that delivers up to 250 m³/h and up to 52 mbar from a 0.55 kW single or three phase motor. It suits air knife drying, blow-off, cooling, and process air, and needs very little maintenance thanks to its sealed bearing assembly. Hurll Nu-Way supplies and services Secomak blowers in Australia.
Steady process air from a compact blower
The Secomak 575/4 is a high velocity centrifugal blower: low volume, high pressure air from a compact, belt-driven unit. It delivers up to 250 m³/h of air and up to 52 mbar of pressure from a 0.55 kW single or three phase motor. It gives the highest pressure in the 575 family.
The 575 is the smallest Secomak high velocity blower, a 0.55 kW unit available in single or three phase. Choose the 575/4 for up to 250 m³/h and 52 mbar on a 0.55 kW motor. Within the 575 family, look at the 575/3 for more flow (up to 390 m³/h).
The fan chamber is machined from aluminium, and the drive belt and sealed bearing assembly keep maintenance to a minimum. It runs on a 50 Hz or 60 Hz supply. Secomak has built industrial fans and blowers in the UK since 1930, and every blower is hand built and tested before it leaves the factory.

What flow and pressure does the Secomak 575/4 give?
Up to 250 m³/h of air and up to 52 mbar of pressure. These are the two ends of its performance curve: peak pressure at low flow, and peak flow at lower pressure. The datasheet shows the full curve.
Should I choose the 575/4 or another 575 model?
Choose the 575/4 for up to 250 m³/h and 52 mbar on a 0.55 kW motor. Within the 575 family, look at the 575/3 for more flow (up to 390 m³/h). Tell us the flow and pressure your process needs and we will confirm the model.
What power supply does the 575/4 need?
Either 230 V single phase or 415 V three phase. It draws 3.5 A on single phase and 1.5 A on three phase.
How much maintenance does a belt-driven Secomak blower need?
Very little. The bearings are in a sealed assembly, so routine care is checking belt tension and wear. Our technicians can overhaul Secomak blowers when the bearings or belt need replacing.
