The Exhausto MDVS 250-500 Submittal Data Sheet describes a mechanical exhaust system for commercial laundry dryers, its components, operation and…
The MDVS 250-500 is a mechanical exhaust system designed to control and maintain proper pressure for multiple commercial or industrial laundry dryers. It is supplied as a complete package that includes an exhaust fan, the BESB Box Ventilator, a Variable Speed Drive (VFD), the EBC30 Modulating Fan Control, a pressure sensor, duct probe and mounting adapters.
During installation the EBC30 automatically detects connections and stores required settings. The system automatically activates the fan when a dryer calls for heat, maintains preset pressure, and enters a post‑purge mode after the last dryer shuts down. Integrated safety functions shut down the system on power or mechanical failure, and a self‑diagnostic panel reports errors.

A call for heat activates the exhaust fan and releases the dryer once the preset pressure is reached; this sequence repeats for each dryer.
The integrated pressure function shuts down the entire system in case of a power failure to the supply fan or the Variable Speed Drive.
