DFX type fan case

Fresh air unit selection basis

In general interior space, to determine the standard of the new air volume depends on two aspects:

personnel

The indoor gas pollution sources

So the room body the small new RP by each most small new air volume index, and the sum of the small new air volume required for per square meter floor) Rb.

Features: 

Selects the high quality air conditioning dedicated fan, satisfies the requirement of long-term continuous uninterrupted operation. Low noise design. Body shell inside all have efficient insulation anechoic material and conform to the requirements of the fire retardant.

Norms diversity, use agile. High qualified steel plate production, both inside and outside surface electrostatic pensu processing, long-term outdoor place no rust.

Use as the plenum chamber: 

Adopt the way of series in the air duct installation, and other ventilation equipment (such as a new trend, fresh air units, modular air conditioning box, air purification box), increase the air pressure in air duct, dealing with air duct is too long, too much resistance and cause the problem of insufficient air volume.

Used as a fan box: independent use, supply air or exhaust for the room.

With the air heat exchange box: provide aerodynamic heat exchange box.

The number of small new air volume = XRp + XRb floor area.

After the Rp (m/h) : 30 to 40

After the Rp (m/h) of 3.6 or higher

Rb is a variable coefficient, the general working environment and values range between 3.6-12.
