VEX4000 - FAN WITH FILTER

The plenum fan provides great flexibility with respect to installation location and spigot position.

This fan type is generally suitable for moderate to high duct pressure drops. The fan creates a static pressure in the plenum chamber, with the outlet opening located in the end or top (size 4010-4050 only) of the unit. On the outside, flanges can be mounted for fitting ducts.

Operating costs

Total efficiency rates of up to 70 % can be achieved with EC motors, allowing operation at optimum rotational speeds. This secures favourable operating costs.

Design options

Units with plenum fans are dimensioned in EXselectPRO.

For each unit size, two motor dimensions are available, allowing optimum operation to be achieved over the whole capacity range.

The filter units are supplied mounted in special frames. They are of bag filter type. The filters meet the requirements of ISO 16850.

Depending on requirements for cleanness and separation, the filters can be supplied in different classes:

- ePM10 50% (M5)

- ePM1 65% (F7)

- ePM 1 65% (FC7)”Pocket City Flo” (filter with carbon, which can remove odours)

- ePM1 85% (F9)

The air handling unit configuration has a pre-filter option. If this option is selected, a 48 mm panel filter can be inserted in front of the bag filter - see the image.

Placing a coarser filter in front of a finer filter reduces soiling on the finer filter. Depending on the outdoor air and the desired quality of the supply air, this can be a good idea/option.

Pre-filters (48 mm) are available in the following classes:

- Coarse 60% (G4)

- ePM10 80% (M5)

- ePM1 50% (F7)

Pressure drop, etc. can be calculated in the product selection programme EXselectPRO.
