Exhaust Fan - Aluminum Die Cast, 300 To 915 Mm Diameter | Dynamic Balancing, High Precision Impellers, Ip 55 Protection, Maintenance Free

PASKO already an acknowledged leader in India for industrial fan manufacturing with its innovative design policy, which includes significant customer involvement, generates Exhaust Fans to guarantee quoted performance figures. Our main objective is to support top quality, value for money products, with the best technical back-up, literature, delivery and after sales service.

The product included in this catalogue is suitable for the following applications :

• Industrial Ventilation
• Condenser Cooling
• Canteen Ventilation
• Transformer Cooling
• Evaporative Air Cooler
• General Exhaust
• Controlled Air Movement

Impellers
The newly designed impellers are manufactured by high precision accurately curved tools to maintain desired blade angles. Each and every impeller is dynamically balanced, tested and packed in the factory through a structured in-process quality control system
Motor
The totally enclosed aluminum die cast heavy duty drive motor with rotor shaft mounted on two permanently lubricated ball bearings is specifically designed to cater desired fan performance with minimum power consumption.
Accessories

• Louvre shutter
• Wire guard
• Wall cowl
• RE units , etc.

Positioning of Fan
The fans should be positioned so that fresh air drawn inside will permeate the entire room. Fans should not be installed in close proximity to doors or windows which are left open. In such cases, the air movement would be short circuited between the fans and adjacent inlets and therefore other parts of the room would remain non-ventilated.

Therefore install the exhaust fan in a window or wall farthest from the door or other openings. Fresh air will then flow over the whole area.

In kitchen, the best spot for the exhaust fan will be in the wall adjacent to, but not directly above the cooking range.

In large occupied spaces, effective ventilation could be achieved if several small fans are installed rather than one or two large fans.

PERFORMANCE

VENTILATION REQUIREMENT
Ventilation implies fresh air supply or extraction of air. The rate of ventilation commonly measured in cubic meter per hour should be sufficient to meet the following requirements.

Extraction of Air
Supply of Fresh Air
A combination of both of extraction and supply.
For a large room it is recommended to use a number of smaller fans at different locations rather than one or two large fans for effective and adequate ventilation.

Mounting
Pasko exhaust fan can be mounted either vertically or horizontally and is suitable for delivering air either from or towards the motor.

Roof Extractor
Pasko Exhaust fans are effectively used as Roof Exhausters as well to dispel air from within a room using suitable and attractive domes fixed on the roof.
