APPLICATIONS
Pressure Operation for BS type Ring Blowers

STIRRING OF ELECTRO-LIQUID
Stir electro-tank with air to make electro-particle flow and get rid of attached bubble. Thus, electro-plating will be quicker and efficiency even.


●SUPPLY OF OXYGEN IN RAISING POND.
●FERMENTATION TREATMENT OF DOMESTIC ANIMALS' EXCREMENT
●HEAVY-DUTY OIL BURNING.
●ANTI-DUST DEVICE.
●BOTTLE WASHER.
●TRANSPORTATION OF DOCUMENTS.
●COLLECTION OF PAPER EDGE.

 

Vacuum Operation for BS type Ring Blowers

NET PLATE PRINTING MACHINE
By use of absorption pressure for fixing to make printing work smooth.

VERSATILE CAPABILITIES FOR VACUUM OR PRESSURE OPERATION  

GENERAL:  

SHOWFOU RING BLOWERS, known also as REGENERATIVE BLOWER, are directly driven by TEFC IP54 Grade F insulation electric motors of Showfou's own make.

As standard equipment, silencers are mounted on the discharge and suction side, thereby reducing noise level considerably. All blower and motor parts are cast aluminum and therefore highly resistant to corrosion. The ribs on the blower housing provide for good heat dissipation, further assisted by the air flow of the motor fan.


SHOWFOU RING BLOWERS are designed for the conveying of air as well as for generating pressure or vacuum. The use of the units for aggressive and toxic media, air of high humidity and medium temperature exceeding 40C is subject to a detailed clarification. The conveying explosive gases are prohibited. If the medium to be conveyed contains solid particles or other pollutions, they are to be removed before entering the blower by installing a filter, or similar device on the suction side.


An increase of the volumetric flow or the pressure may be achieved by connecting two blowers either in series or in parallel.
If connected in series, the pressures are added whereas the volumetric flow remains the same. If connected in parallel,
the volumetric flow rates are added whereas the pressure remains the same.
