Description
The HEPA Supply Air Fan Unit is a complete Fan-Filter air movement system incorporating HEPA Filtration up to grade H14 to EN1822. This Air Handling Unit can be fitted as a standalone supply or recirculation HEPA filtration system, or retrofitted and balanced to work with an existing mechanical ventilation system such as a fan coil system or air conditioning systems which do not have an existing ability to support HEPA filtered air.
The HEPA Supply Air Fan Unit is fitted with a high pressure and speed adjustable EC fan which is wired to an external terminal box to which power connections and speed adjustments can be made manually via a 0-10V signal potentiometer.
The HEPA Supply Air Fan Unit is manufactured in a standard Air Handling Unit construction with an anodised aluminium pentapost frame, fitted with double skinned mineral wool insulated panels. The unit is finished with a grey plastic-coated leatherette steel. A single removable access door provides access for changing the HEPA and any pre filters, and also allows for fan inspection and easy cleaning.
