DamaTajhiz Backward Centrifugal Fan (Non including Electromotor)

  1. Dama Tajhiz Backward Centrifugal fans are extensively used for air exhaustion or air supply ???/ in all cases even transfer of materials-powder ???? . Single-blades are backward, flat , curved and produced with airfoil section.
  2. Centrifugal fan, spiral fan with backward-curved blades (backward type in direct coil models and pulley belt.
  3. Backward propellers are produced single/double inlet models and have better efficiency compared to forward propellers and has not speed restriction of propeller.  
  4. All Dama Tajhiz fans are equipped with double chassis and absorber.
  5. For information on coefficient of air exhaust unit in Dama Tajhiz Backward Centrifugal Fans, the following table can be used: 
  6. To assure the desirable performance of fan at installation place, consider the following terms and cases:
  • Permissible sound level
  • Altitude
  • Moisture and installation place
  • Moisture (humidity) and temperature of gases entering to fan
  • Existence of dust or alkaline or acidic gases
  • Continuous work time of fan within 24 hrs. and or other particular conditions

In order to order DamaTajhiz Backward Centrifugal Fans, the following cases should be considered:

  • Design of foundation and vibration correction for industrial units
  • System type: A- Direct couple, B) Foley Belt
  • Type of system: A-Spiral (Screw)B) Ceiling
  • Type of Propeller: A- Forward B- Backward
  • Consumable sheet: A- Galvanized B)Oily
  • In case of Foley Belt of type of bearing: A- ucp , B- SN
  • Selection of output angle of spiral fan ((helical fan)
  • Looking through the outlet opening at spiral fan, we can find fan inlet direction

All Dama Tajhiz fans are provided with 12-month warranty and 10 years of after-sale-services. The customer should install products and in case of request for installation by the experts, its expense shall be separately calculated. All bearings used in production Dama Tajhiz Centrifugal Fans are made in Japan or Germany. Shell of Dama Tajhiz Centrifugal Fans is made of galvanized sheet.  The price of electromotor is not included in the prices posted on the site. Contact Sales Dept. for information on electromotor prices.
