VM-25 Miniature
Air Vibrator
The
VM-25 miniature air vibrator produces 16,000 vibrations per
minute while only consuming 2.0 SCFM (57 lpm) of compressed
air at 80 psig (5.4 bar).
Its size and high frequency vibration make the VM-25 excellent
for automated parts track vibration. It can also be used to
promote the free flow of materials from small, thin-skinned
(minimum 28 gauge) bins and hoppers up to 2 cubic feet in
(57 L) capacity. They can be supplied with a muffler to prevent
contamination and reduce noise level. An air-cushioned
version, VMAC-25, will further reduce noise level, but at
a reduced force output.
Normal output is 15 lbs.
PMA
Rapper
Model
PMA rappers are designed for electrostatic precipitator applications.
They have proven to be most economical, yet effective devices
for these difficult applications. They produce higher frequencies
while consuming less air than similar products. The PMA features
a tapered mount that conforms to most rapper shaft and adapter
designs. These vibratorsare internally coated for enhanced
performance.
The PMA's technical data is as follows: length 13" (33.0 cm),
diameter 4.5" (11.4 cm), piston diameter 3" (7.6 cm), inlet
port 3/8" NPT, output ports (2) two 1/2" (1.2 cm), weight
40 lbs. (18 kg), frequency 3000 VPM, air consumption 8.3 SCFM
(235 lpm) and normal operating pressure 20 to 40 PSI (1.4
to 2.7 bar).
Models
FEP & VMRAC-EP
Model
FEP and newer-model VMRAC-EP vibrators feature
a specially machined "extended piston". The piston extension
has a threaded portion enabling it to be secured to the object
receiving or transmitting vibration. They can
also be used as a simple rapper with orwithout a rubber bumper
attached to the end of the piston extension. These vibrators
are internally coated for enhanced performance. The
VMRAC-EP has the same basic design features as our Model
VMRAC.
