Heat Recovery Fresh Air Ventilation Unit
The unit's fan is a double-inlet, double-width forward-curved centrifugal fan, which has undergone strict static and dynamic balance inspections, with a balance accuracy not lower than the ISO1940-G4.0 standard.
The unit's fan uses tapered sleeve bearings to reduce vibration issues that are typically caused by eccentric lock bearings, and the bearings have a designed service life of more than 75,000 hours.
The main components of the unit's fan: impeller, shaft, casing, and heat exchange core, have a service life of not less than 15 years under normal use.
The unit's motor is a fully enclosed three-phase asynchronous motor.
The entire machine operates with low noise, high efficiency, robust structure, and stable performance.

Technical Parameter
Dual Filter Net
Both the fresh air and exhaust air sides are equipped with washable filter nets that can be reused and are easy to install and remove.
Variable Frequency Three-Speed Motor
Features high energy-saving, high efficiency, long lifespan, low vibration, and low noise.
Forward-Curtained Centrifugal Fan
After dynamic and static balance testing, the balance precision is higher than the ISO1940 - G4.0 standard, ensuring stable operation.
Heat Recovery Core
The core is made of specially coated aluminum foil material, which is corrosion-resistant, prevents condensation on the membrane, has a long service life, and achieves a heat exchange efficiency of over 70%.
Galvanized Sheet Inspection Hatch
The entire unit is made of galvanized steel plates, which are corrosion-resistant and anti-aging, with inspection hatches that are easy to use and filters that are convenient to replace.
Two-Way Air Exchange
Silent design ensures a continuous supply of fresh air.
