The HPD450 & E490 are compact, high efficiency, low discharge temperature units & offer 100% oil-free air delivery. These rotary vane blowers can overcome high pressure drops, and high altitudes, and are for use on trailers with small air pads.
Either model can be configured for mobile or stationary operation while providing completely oil-free air delivery for pneumatically conveying cement, lime, gypsum, or other fine, dry bulk materials.
The HPD450 and E490 rotary vane dry truck blowers are economical, lightweight, and is a high-performance solution for offloading dry bulk materials

Sliding vane technology maintains consistent airflow, delivering some of the fastest unloading times in the industry.
Clean air delivery protects product integrity and reduces downstream contamination risk.
Among the lowest operating temperatures in its class, supporting component longevity and system reliability.
Despite the wide performance range, the size and shape of the machine make low-cost direct driving possible.
Electrolytic nickel-plated rotor provides corrosion resistance and long service life.
Simple grease-lubricated bearings and wear-compensating vanes reduce maintenance costs and downtime.
The HPD450 / E490 Series is ideal for fine, dry bulk pneumatic conveying applications, including:
These blowers are especially effective on trailers with small air pads or systems with higher pressure losses.
