BINMASTER AIRPAD
PHYSICAL SPECIFICATIONS
AIRPAD SELECTION GUIDE
For best results, locate the lower air pads as close to the discharge outlet
as possible. If material is held in the bin for a long period or compacted in
transport, we recommend air pads be installed on 12” centers.
Generally 4 rows of air pads on 12” or 15” centers are recommended. On conical
bins these rows are spaced equally On pyramidal bins the rows are spaced
equally on the sloping sides or in the valleys of the material if the material
tends to hang up in these valleys.
AIR SUPPLY
The air supply must be clean and dry. We recommend positive displacement and low pressure blowers. Plant air can be used but the pressure must be reduced to 3 – 5 psi and a filter or moisture trap must be used on the low pressure side. The use of plant air can be a limiting factor due to the volume of air needed.
INSTALLATION
Drill 7/16” holes through the bin wall on the predetermined centers.
Insert the special tank nipple through the hole and lock it into place with
the locknut. The rubber gasket and spacer washers are furnished.
