Water-Cooled Air Blowers are similar to air-cooled type blowers in construction and performance-except for the addition of a cooling arrangement.

In water-cooled blowers, the main casing and side plates have water jackets around them. Through which water is circulated, which dissipates the heat generated and keeps the internals cool. Water-cooled blowers are recommended for applications where discharge pressures exceed 10-psi (or 7000-mm WG).

In applications where the differential pressure is in excess of 10-psig, it is both essential and recommended to dissipate the heat for efficient working and longevity of the blower bearings and seals. These blowers have a unique design of single inlet and single outlet for cooling water and no cumbersome water pipe connections externally. Internal circulation of water to various areas is achieved through in-built channels. This unique design makes the operations very simple, yet very effective. The cooling water inlet is at the bottom so that the water rises up against gravity, reaching all the corners before it comes out from the outlet. The flow rate of cooling water required are low.

Blowers manufacture a standard range of cast iron air blowers. The range covers capacities to 6931 cfm (11749 m3/h). These blowers are designed and built to provide reliable, long life, oil free operation at a competitive price and can be supplied as bareshaft for OEMs or as complete packages.

HINDUSTAN BLOWERS Blowers also offers an extensive range of standard air blower packages for a wide variety of applications and industries. The main applications are water and sewage treatment and pneumatic conveying. HINDUSTAN BLOWERS air blower packages include all the standard accessories such as silencers, filters, valves, drives and acoustic enclosures, as required. Each HINDUSTAN BLOWERS air blower package is tested before dispatch.

Positive displacement vacuum pumps/booster are used to create low vacuums. This type of vacuum booster, expands a cavity and allows the gases to flow out of the sealed environment or chamber. After that, the cavity is sealed and causes it to exhaust it to the atmosphere.

Our mechanical Vacuum Booster are positive displacement pumps with two figure eight shaped impellers rotating in opposite directions inside the casing. As each lobe of an impeller passes the blower inlet, it traps a quantity of air equal to exactly one fourth the displacement of the blower.

This entrapment occurs four times per revolution. The entrained air is forced around the case to the blower outlet. Timing gears accurately position the impellers in relation to each other to maintain the minute clearances so vital to the high volumetric efficiency of the pump.

HINDUSTAN BLOWERS range of aqua culture blowers to meet the growing demand for aquaculture/horticulture for RASTanks / biofloc system / natural fish pond requirements which essentially demand JOOP oil-free Air. These blowers are totally dry machines where lubrication chambers are physically isolated from the main air chamber ensuring 100% oil-free air delivery. The oil-free air delivery ensure for proper maintenance of Biologica! Oxygen Demand(BOD) for aqua culture.

Acoustic hood covers the complete blower and motor arrangement. Its fully sound proof cabin decreases the overall sound of the system to the accepted norms as per IS specifications. Provision of exhaust fan decreases heat in the chamber and fixing of the anchor bolts results in rigid base to the acoustic hood. This is a very effective enclosure to provide noise reduction of 15 to 20 dBA or more, to comply with international noise level & is available for all blowers and models.
