Channel Frame Installation
1. Cut filter length to fit frame opening:
Count marks to length the frame opening and cut. (i.e. 10 ft wide frame opening, count 10 marks and cut on the 10th mark; i.e. 3 m wide frame opening, count 9 marks and 6 pleats, then cut).
To cut, slide knife under pleat (and polyester if cutting the HE). After knife is in position, firmly grasp the filter and lift knife.
2. Gather filter:
Filter into a tight accordion for easy transport. Slide filter into frame, white side facing toward spray gun. Release.
3. Tuck first and last pleats:
Behind clips on each end of exhaust frame.
Do not over-extend the filter.
Over-extension reduces arrestance efficiency and filter life.
You will cut through two paper layers (plus syntetic material in the High range). Pinch the pleats on either side beneath the knife for additional control while cutting.
Do not over-extend the filter.
Over-extension reduces arrestance efficiency and filter life.

Exhaust frame construction
Three simple elements constitute the Andreae Filter frame:
1. An L-shaped channel is positioned at the side and bottom of
the frame to create the filter stand support.
Dimensions:
Outside height 1 1/2 (3,81 cm) width 3’’ (7,62 cm), Length as required.
Inside 2 13/16’’ (7,14 cm)
2. The side clips secure the first and last filter pleat in place
and seal the exhaust wall
3. A U-shaped channel is positioned upside down to create the upper part of the frame. This seals the top of the filter and prevents the filter from falling forward when the ventilation is turned off.
Dimensions:
Outside height 1 1/2 (3,81 cm) width 3’’ (7,62 cm), Length as required.
Inside width 2 5/8’’ (6,66 cm)
Andreae Filters are held in place by an inverted U-beam on top and an L-beam on bottom. If the booth has several rows of filters, each row is installed on top of the adjoining beam.
The inner dimensions between the U and L beams must be sized ~0.2”” more than the actual filter height to allow room for the filter to slide into the frame.
