Direct Drive Centrifugal Blower Fan with 5.5-850kw Motor Power Range for Factories

We've been shiping these to heavy industiral operations for years now—basically any factory needing to move serious volumes of air under pressure will find it does the job. You can use it for forge ventilation, conveying dust-laden material, or just keeping a large workspace clear of fumes, and it handles particles up to 150mg/m³ without choking up.

Motor power runs from 5.5kw all the way up to 850kw, which is a pretty wide spread, and you've got three speed options at 960, 1450, or 2900 rpm depending on what your process needs. Air volume goes from about 2198 to 123090 m³/h, with static pressure from 3407 to 16250 Pa—so it's not a light-duty unit, and most buyers go with the higher speeds for forge applicaion. The frame is aluminun, blades are stainlss steel, and it's direct drive so there's fewer belts to replace.

One thing we get asked is whether it runs hot—standard temp resistance is 50°C, but it'll take up to 80°C without issue, and we've had a few shops push it beyond that with custom builds (usually 2-4 weeks lead time for those). It's not meant for explosive or corrosive gas streams unless you spec the sealed variant, which we can quote separately.

We usually have stock on the common motor sizes in the 30-200kw range, but big stuff (anything over 500kw) is typically made-to-order, so confirm lead time before you budget. Payment terms are 30% deposit, balance before shipment, and our company can do T/T or L/C for larger orders. ISO and CE certs come with every unit, and you'll get a COA with the test data for pressure and airflow at your specified rpm.

Also, the blades are adjustable—you can tweak the angle slightly to shift the pressure curve if your ducting changes, but it's not something you'd do daily. The color options are blue, yellow, green, or whatever you want if you're ordering a batch of five or more.
