Amplification
ratios (entrained air to compressed air) of 30:1 are achieved with
the Standard Air Knife, compared to 3:1 for drilled or slotted pipe.
Air savings of 40% to 90% are possible when replacing these "homemade"
blowoff devices. Pay-out is normally measured in weeks, not months
or years.
Specifications
The Standard Air Knife is available
in six standard lengths of 6", 12", 18", 24",
30" and 36" (15, 30, 46, 61, 76 and 91cm). Special lengths
up to 36" (91cm) and unlimited system lengths are available.
Any number of Standard Air Knives may be installed across a given
area.
Filtration:
The use of clean air is essential. Kits include an automatic drain
filter with a 5 micron filter element that is sized properly for
flow.
Materials of Construction:
The Standard Air Knife is available in either aluminum or stainless
steel construction.
Regulation:
A pressure regulator on the compressed air supply provides infinite
control of flow, force, and air consumption. Kits include a pressure
regulator that is sized properly for flow.
Shim Sets:
A Standard Air Knife has a .002" (.05mm) gap setting. This
gap is set with a shim positioned between the cap and body of the
Standard Air Knife. Force
and flow through the Standard Air Knife may be easily increased
by adding shims to open the gap. Kits include a shim set (three
additional shims). |
