2 Company profile After years of hard working, Toofansaz Kerman is proud to offer the engineers and technicians of cooling/heating systems and producers of food dryer machinery, 0 different types of centrifugal fans, hoping to keep it s customers satisfied and take a step forward to the independence of Iran in this regard. Specifications of Toofansaz fans: Cost-effective compared to the foreign models High efficiency and low power consumption Prompt delivery and after-sale services Offering a wide range of choices and customizations for special uses Since Iranian engineers, experts and technician s are familiar with Italian Nicotra products, TSK has tried to produce fans of the same size to make it easier for the customers to use them. TSK guarantees the use of galvanized corrosion/rust-resistant in production of it products. TSK hopes to see you as one of it s customers for many years to come. nj» kã²¼u r¼ãÿäotºiw Î Ïk Âw ph yãm oã«ãq x U I ²Iw ph uq jnhj nihtîh I o piw IÎ¼ö S o{.

Fan Laws Fan laws can apply to any range of fans of geometric similarity FOR CONSTANT FAN SIZE AND DENSITY: I. Volume varies directly as the speed ratio: - V 2 = V 1 N2 N1 II.

Volume varies as the cube of the ratio of fan sizes: - V 2 = V 1 D2 D1 II. Pressure varies as the square of the ratio of fan sizes: - P2 = P1 D2 D1 2 III.

Whether you are looking for low noise, high efficiency, or the security of fans designed and built for the long haul, TOOFANSAZ Fans has pioneered since 1981.

6 Whether you are looking for low noise, high efficiency, or the security of fans designed and built for the long haul, TOOFANSAZ Fans has pioneered since near 20 years of experience, Toofansaz is one of the largest and longest established manufacturer of centrifugal fans. TDF (Double Inlet Centrifugal Forward Fan) [with 2 types of housing] Forward-curved centrifugal fans are special in that they deliver considerably more air volume and also produce higher static pressure than backward centrifugal fans of the same size and speed.(but at the lower efficiencies)(fan Handdook) Volume flow from m/h to m/h Total Pressure up to 1.

-They have high structural strengh so that they can run at high speeds and produse up to 0 in. WC of static pressure.

14 TBA (High Performance Double Inlet Centrifugal Fans With Airfoil Blades) Airfoil centrifugal fans are the deluxe centrifugal fans. They have the following features: 1-They have the highest efficiencies of all centrifugal fans. 2-They have low noise levels. -They have high structural strengh so that they can run at high speeds and produse up to 0 in. WC of static pressure. -The blades are made as hallow airfoils of steel it can be obtained the highest efficiencies in the all types of airfoil fans.[2] 5-Volume flow from 000 m/h to.000 m/h 6-Total pressure up to Sizes from to.
