Republic offers a
complete line of regenerative blowers for high vacuum
or compressed air applications in both horizontal and vertical mounted
positions. Air flow capabilities range from 50 to 776 CFM, vacuum capabilities
from 47" to 236", and pressure capabilities up from 47" to
307". TEFC electric motors are cUL and CE certified and come in
single and three-phase, dual frequency, and multi-voltage versions
for worldwide applications. Horsepowers range from 1/2 to 50 HP(from
0,4 to 37kW).
Republic
Regenerative Blower configurations are
available in either single (one impeller) or double (two impeller)
stage. The impeller is directly connected to the motor
shaft, providing powerful force without undue friction. The bearings
are outside the compression chamber, ensuring maximum operational
reliability under high differential pressure.

This
low-maintenance, oil-free design provides continuous, dependable service
to our customers. NOTE: Explosion-proof and chemically-treated
blowers are available.

Operating
Principle
Air
or gas is pulled into a side channel (1) through the air inlet (2) and
is accelerated by an impeller (3) rotating inside the impeller chamber
(4). The resulting pressurized air or gas is discharged through the exhaust
outlet (5). This type of operation is also known as a "ring" blower
design.

Cleaning:
When dust or residue is evident, clean the entire surface of
the blower. Lubrication:
After approximately 20,000 hours of operation, or 18 months,
replace the grease in the bearings.
Installation
Units
can be installed and mounted in any axial direction. For quiet
and vibration-free operation, install the unit over a rubber
pad. Do not obstruct the cooling system of the motor. Keep all
ventilation gratings open and clear. Minimum clearance (1.5")
must be maintained between the unit and all side walls or other
barriers. Keep all flammable gases and materials away from the
unit. After installation be sure to tighten the eye-bolt. The
system voltage and frequency is the same as stated on the rating
plate +/-5% voltage and/or +/-2% frequency deviation from the
rated value without reducing output. Connections should be arranged
and attached according to the circuit diagram on the terminal
box. The ground wire should be connected to the grounding terminal.
General
Notice for Republic Regenerative Blower
Republic Regen Blowers are designed for handling air and nonflammable,
non-corrosive, non-explosive gases. These regen blowers are designed
for continuous use. Applications involving frequent temperature
changes should be evaluated by our technical department prior
to installation. Maximum ambient temperature at the inlet is
104 ºF (40ºC). Intake filtration should be used to
eliminate solids and impurities from entering the blower.
