FS-Curtis BWV30 40 HP Oil-Free Variable Speed Rotary Screw Blower

The FS-Curtis BWV30 is a 40 HP (30 kW) oil-free, variable-speed rotary screw blower, an enclosed, base-mounted package that delivers up to 632 CFM of 100% oil-free air. Direct-driven by a high-efficiency permanent-magnet motor with variable speed control, the BWV30 matches output to demand for low energy cost and quiet, reliable operation.

Backed by more than 170 years of FS-Curtis engineering and a nationwide network of factory-trained service technicians, the BWV Series is built for continuous-duty industrial service. Its oil-free helical twin-screw airend makes it ideal for applications that demand clean, contaminant-free air: wastewater treatment and aeration, pneumatic conveying, cement and bulk material handling, mining, and food processing.

Air Flow by Discharge Pressure

Available at 11.6 psi, 17.4 psi. Specify your discharge pressure when ordering. Order codes: 11.6 psi (0.8 bar) = FBW30AAX4WXPC; 17.4 psi (1.2 bar) = FBW30AAX4ZXPC.

Key Features

100% oil-free air: an oil-free helical twin-screw airend delivers clean, contaminant-free air where oil carryover is not an option.

Variable-speed permanent-magnet motor: a high-efficiency PM motor with variable speed drive matches air delivery to demand, cutting energy use across the load range.

Direct drive: a direct-coupled drive maximizes transmission efficiency and reduces maintenance versus belt or gear arrangements.

iCommand-Touch+ controller: a 7-inch full-color touchscreen with trending, graphing, and higher-level plant communications.

Enclosed low-sound package: a base-mounted, sound-attenuated enclosure keeps the blower quiet enough for installation close to the work area.

Air-cooled design: no cooling water required, simplifying installation and reducing operating cost.
