Handlair Engineers Pvt. Ltd Shivalik, Delhi

  HANDLAIR wet type dust collectors are used for a variety of applications. The venturi type scrubbers do not require a water circulating pump, and are widely used for collection of coarse dust, where the dust settles in water without getting solved. These are normally installed in coal handling plant and ceramic industries. Spray type scrubbers are ideal for fume exhaust and are widely used for industrial fume exhaust applications as well as for commercial kitchen exhaust.

Roof Extractors are basically axial flow fans meant for extracting hot/stale air at the roof level from large halls. These fans are widely used in boiler and bunker houses of power plants, steel plants, cement, automobile industries, These are generally supplied with exhaust hoods to prevent entry of rain water, birds etc.

HANDLAIR oil bath filter units have been developed for installing with ventilation plants, where the dust concentration in the surrounding air is comparatively heavier. It is very ideal for ventilation systems in coal mines, steel plants, cement plants, foundries and similar industries. These filters are available in different sizes, depending on the capacity. This can be either direct or indirect driven. Each direct drive unit can be coupled with two indirect driven units, depending of the size. In this filters, the dust is retained by adhesive action, when the dust laden air passes through the filter mat. The mat is cleaned and re oiled as it passes intermittently through the oil bath. Drops of oil that may be carried through are trapped by the oil drop eliminator.

Mancoolers are designed for large air volume discharge with high velocity and for long distance sweep. These can be used in various applications such as furnaces, electrical equipments, spot cooling and for general ventilation in shop floors. These man coolers are available in three different models:- Pedestal type, Column mounted type and Tubular type.

Handlair Prefilters are available in several configurations.They are completely washable, with pressure drop at rated flow less than 2.5mm WG and effciency greater than 90% down to 10 micron when tested as per relevant norms.

HANDLAIR Cyclone type dust collectors named after the weather phenomenon are large tunnel shaped metal tube connected to ducts often used in a large variety of industries, where , the emission level requirements are not stringent. These types of units are also used before bag filter type dust collectors as pre collectors, where, the dust generation is quite high and emission levels are restricted.     Dust particles are sucked in at the top side. Air containing fine dust, blows out while the chips and large dust particles fall out through the bottom in to a drum or a screw conveyor. Blown out five Dusty air is filtered again, using media filtration or wet scrubber as per requirement. These are generally used in, Foundries, Metal spraying, Pneumatic conveying, Cement Industries, Food Processing, Zinc Spraying, Recycling, Powder coating, Shot blasting, Wood working, Pharmaceuticals,Transfer points, etc. HANDLAIR cyclone type dust collectors are widely used for a variety of applications like grinding, polishing, buffing machines etc. The capacity of these units ranges from 300 cu.mtr/Hr to 50000 cu.mtr/Hr. In single as well as in multiple units. HANDLAIR unit type dust collectors comprises of compact dust collectors complete with centrifugal blower, its driven motor, dust collection bin and supporting frame work. These units can be supplied either in mild steel or stainless steel construction as per requirement. These dust collectors are ideal for using with a wide range of applications like grinding, polishing, buffing operations etc.

HANDLAIR manufacturers centrifugal blowers for a wide range of applications viz:- Air cooling, Flour Mills, Foundries, Fertilizer, Fume Exhaust, Paint Booths, Paper Mills, Pneumatic Conveying, Rice Mills, Steel Plants etc, and many more applications, where the air is to be cleaned or moved for different purposes for a healthy working environment, and quality products. These are offered in capacities from 200 cu.mtr/Hr upto 1,75,000 cu. Mtr/Hr with pressure upto 1200 mm.wg. These are offered in different material of construction like mild steel, stainless steel and mild steel with FRP coating. Impellers are of various designs to suit different applications and are dynamically balanced for vibration free operation.

HANDLAIR Bifurcated fans are direct driven axial flow fans, where the motor is encased in a metal box to isolate it from the airflow. This makes the bifurcated fans ideal for exhausting or recirculating of hazardous / chemical fumes , gases in high temperature , or for such conditions, where the motor needs to be isolated from the air stream.

Bag filter type dust collector is a reliable and economical unit with high efficiency, widely used for metal grinding, polishing, buffing, mixing etc. These units are also widely used in tablet making machines, tea and food industries. These units are provided with high efficiency filter bags, in polyester /poly propylene needle felt media in plain as well as pleated construction. The capacity of these units varies from 500 cu. meter per hr to 50000 cu. meter per hour. The filter bags are cleaned with a pulse of compressed air which is initiated by electronic timer and a series of solenoid valves.

Axial flow fans are used for a variety of applications, such as Generator ventilation & Generator sound proofing, Air cooling, Ventilation for General engineering industries, Mining, Tunnel ventilation, Humidification plants, Textile mills, Driers Fresh air and Exhaust applications. These fans are widely used as spot coolers, Roof Extractors, and Man coolers. Two stage fans are manufactured for mining and tunnel ventilation applications. HANDLAIR Axial flow fans are offered for capacities ranging from 1000 cu.mtr/hr to 1,75,000 cu.mtr/hr with pressure up to 80 mm wg, in sizes ranging from 300 mm to 1600 mm diameter.

The basic principle of HANDLAIR air cooling unit / air washer units is that the taken in and filtered for its particulate matter by suitably designed filters. The fresh, filtered air is then made to pass through specially designed honeycomb structure of cellulose paper fills media, which has water absorbing properties. The air when passes through the fill media, absorbs the water and loses heat in the process. This makes air cool, which when supplied to the work area, provides comfortable conditions inside the work area. These units are available with capacity varying from 2500 cu.meter per hour to 2,00,000 cu.mtr/hr with combinations of single and multiple blowers. Air cooling units are also manufactured with spray type cooling sections, as per customer requirements. The unit chamber is normally fabricated with standard G.P. Sheet and powder coated for longer life. These are available in single skin as well as in double skin construction.
