Pullman Engineering Systems Pvt. Ltd.

Andheri West, Mumbai, Maharashtra

We are offering ventilation systems, pressurization systems etc. These systems are designed based on the area to be ventilated, heat load, number of persons in the area, type of roof, number of doors and windows for various types of industries, basement of malls to bring about desired number of air changes per hour and consist of providing fresh air supply blowers fitted with inlet filters to supply filtered air distributed through dustings controlled through grills and effectively exhausting out foul air. these systems can be provided along with evaporative cooling arrangements

These are mainly recommended for industrial ventilation and fume exhaust requiring high volumetric flow rates at low pressures.Range: Capacity up to 1, 00, 000 cmh. and pressure up to 90-mm w.g.Construction: Casing & drive stands are fabricated in mild steel, casing is of tubular shape having enough length to cover motor and impeller.Drilled flanges are incorporated at Inlet and Outlet. The impeller is of axial flow type with aerofoil design and statically and dynamically balanced. It is usually in cast aluminum. These fans are supplied either in direct or V-belt drive arrangement.

pullman industrialfans, blowers & exhausters, owing to their high efficiency and good workmanship, are widely used by various industries like chemicals, fertilizers, pharmaceutical, plastic, food processing, steel, mining, textile, engineering, research laboratories, hospitals and hotels, wood-working unit, cement plants epic.

these are available in different materials of constructions such as ms, ss and aluminum etc. Depending upon the working conditions: and are classified and are recommended on the basis of the applications, following are the types ofpullman fans, blowers & exhausters.

pullman centrifugal high pressure blowers applications: these are extensively used and are most suitable for pneumatic conveying systems, flotation systems, liquid agitation, air slide fans for cement plants and numerous process applications requiring high pressures as well as for delivering air blast to furnaces, boilers etc.range: capacity up to 50, 000 cmh. And pressure up to 1, 500-mm. W.g.
construction: constructional features are similar to those of blowers and exhausters but however, the impeller is of backward curved design which is suitable for developing high pressure.

pullman centrifugal medium pressure blowers applications: used for fume extraction, dust collection, pneumatic & material conveying and in various process applications.range: capacity up to 1, 00, 000 cmh. & pressure up to 500-mm w.g.construction:. Supplied in only (sisw) & are fabricated in heavy gauge steel sheets with adequate framing of ms angles, drilled flanges are incorporated at inlet & outlet.
the impeller, depending on the type of use, could be of backward inclined or radial design, statically & dynamically balanced for minimizing vibrations, drive arrangements in which blowers & exhausters are supplied are direct drive, direct drive through coupling or v-belt drive to suit specific requirements.

pullman centrifugal low pressure blowers applications: these are suitable for industrial ventilation requiring high volumetric flow rates at low pressures.range : capacity up to 5, 00, 000 cmh. And pressure up to 150-mm w.g.construction: fans are available either in single inlet single width ( sisw) or double inlet ( didw) type fabricated in mild steel sheets and stiffened by means of ms angles, at inlet & outlet drilled flanges are incorporated for easy connection of the fan to the system.
the impeller is of backward inclined design, statically and dynamically balanced and mounted on the shaft by means of cast iron hub. Drive arrangement could be direct or through v-belts depending on a specific requirement.

POWERED VENTILATOR These are available for 3 different types of mounting on the roof i.e. flat, slope, ridge type. It consist of a bottom barrel in which is encased a cast-aero foiled section aluminum impeller directly mounted on the shaft of flange mounted TEFC motor & on top of the Barrel is a hood having bird-screen. It is available in sizes from 12" to 48" & is light weight, Low RPM highly efficient for exhausting out hot & foul air that remains suspended in the plant. TURBO VENTILATOR The turbo ventilators are available in sizes 28", 32" OD and consist of aluminum fins, Top cover, bottom ring, shaft, supports in stainless steel with FRP base.
