PLASTIC BLOWERSPLASTIC BLOWERSPLASTIC BLOWERSPLASTIC BLOWERS

The Plastic Centrifugal Blowers are

designed to provide efficient,

economical & maintenance free service

in the corrosive ventilating & processing application. The

selection and design of Blowers for corrosive application is

a very specialized because of corrosive nature of air stream

and mechanical design of impellers in varieties of plastic

materials like - PP, PVC, FRP etc.

We are working with Blowers for corrosive application

including ventilation requirements since 1983. During this

span, we have acquired considerable know-how and

experience in Blower technology.

Coated M.S + FRP / PP / Rubber lining blowers suffers

from cracks or pinholes the coating is usually thin, it

subjects to erosion at leading edges of blades, hencegeneral failure sets in. The result ? Corrosion, Reduced life,

Concern of plant safety. Legal authorities walk in. And you

begin with whole lot of problems to solve thereafter. With

invention of plastics like polypropylene (PP), FRP (fiber

glass reinforced plastics) a new order is put in Blower

technology. Corrosion resistant property along with ease in


2/4

fabrication for intricate shape, make PP / FRP Blowers very

useful in corrosive applications. Above all, the strength-to-

weight ratio is higher than steel, hence starting torque,

power consumptions are less compared to steel Blowers.

We are designing the Blowers at the optimum RPM,

including blade designs / angles which insures best

efficiency and hence least power consumption with

minimum maintenance. The Unique feature of FRP Molded

impeller is that it is light in weight which minimizes the all

usual Blower's mechanical problems.

ESSENTIAL TECH. INFORMATION MUST FOR EVERYESSENTIAL TECH. INFORMATION MUST FOR EVERYESSENTIAL TECH. INFORMATION MUST FOR EVERYESSENTIAL TECH. INFORMATION MUST FOR EVERY

USERUSERUSERUSER

The essential function of blower is to provide the

required air / gas flow against the resistance of the

associated ducting and cleaning devices like scrubbers,

dust collectors etc.

The user must always know that blower can have large

number of operating point along the length of itscharacteristic curve, varying from 'Static No delivery' to

'Free delivery'. However when the blower is connected to

ducted system, the operating point can only be that point

where the system resistance curve intersects the fan curve

as indicated in figure 1figure 1figure 1figure 1. Nowadays the Backward bladed

blower is most widely used because of its useful feature of


3/4

self limiting power curve, the power requirement reaching a

peak at a flow rate some what higher than the normal

selection point and thereafter decreasing with further

increase of flow - as shown in figure 2figure 2figure 2figure 2. Please not6e the

system resistance / pressure drop will depend on layoutdetails like duct size and its length, velocity, number of

bends, pressure drops in hoods, scrubber / dust collector,

chimney etc. Volumetric capacity depends on the

application's exhaust & ventilation requirements. If you are

unable to estimate the pressure drop and required capacity

/ volume, then let us know these details of layout.
