design is based on Moorfields fan filter units that are the backbone of the
successful Clean-Tent range of products. The Clean-Shower is a laminar down
flow booth designed for use in clean rooms to create a micro climate of
approximately two levels better residual particulate quality w.r.t. ambient
The Fan filter
unit consists of an epoxy coated steel air box housing a centrifugal fan and air
dampers /baffles. At the back of the box is a 400mm square spigot containing pre
filter and ( if required) flange connection for a supply air duct. On the front
of the unit is attached the final filter. This determines the quality of the air
supplied. The filter is attached to the frame via a neoprene seal and
siliconed into place. H14 Class 100 HEPAs are fitted as standard but other
options are available upon request.
The fan is
controlled by a variable speed rotary dial and on/off switch mounted on a dado
rail attached to a vertical support leg. The fan can provide up to 1100 m3
/hr through the filter at the industry standard 0.45 m/sec face velocity.
This ensures that the air change rate at the work station is very high for the
specified Class specification.
The fan filter
unit is mounted on a structural T grid roof on top of a 50mm box section
anodised aluminium frame. The frame is enclosed on all sides with clear strip
curtains / solid acrylic panels (customer option), designed to allow as much
ambient light into the work station as possible.
