Zero Leakage Blowers, and Fans
Northen Industrial Co. develops varios types and sizes of gas-tight and zero leakage fans and blowers for containment of hazardous organic and inorganic compounds in industrial process plants and other critical applications. Special construction and shaft sealing devices are available for blower service requiring zero or minimal gas leakage into and out of casing.
Northen Industrial Co. has a lot of experince with gas-tight and zero-leakage construction on fans and blowers, including: multistage lip shaft seals; Buna-N, Viton and Teflon seals; mechanical shaft seals; special fan housing gasketings; single and double carbon ring seals; hermetically sealed blowers; magnetofluidic and ferrofluidic seals; and packed stuffing boxes with barrier liquids and purgeable seals.
Specific code welding processes and special fan design features are used too - to ensure complete gas tight integrity.
Zero leakage and gas tight fans and blowers could be used in the following industries:
* Pollution Control
* Pulp and Paper Industry
* Printing and Converting
* Chemical Plants
* Power Generation
* Research and Development
* Petroleum
* Food Processing
* Paint and Ink Industries
Some special materials and alloys frequently used in gas tight fans, especially for service in hazardous, abrasive, corrosive and high temperature environments, include:
Corten, ASTM A36 Carbon Steel, Hastelloy, Inconel, Stainless Steels of different kinds, Titanium, Monel, Aluminum, Teflon, Rubber LIning. These materials are typical for industrial applications requiring high strength alloys and super alloys too.
As an intermediate step between standrard fan design and air-tight design, Northen Industrial offers a few stages of low leakage construction on fans and blowers - for industrial cusomers calling to minimize leakage fans due to the presence of toxic or corrosive gases in the airstream. As some system requirements are more stringent than others, and since some of the necessary modifications can be rather expensive, a few levels of Low Leakage Fan Construction are offered to choose from:
1) Heavy gauge housing construction with solid housing drive side, Neoprene Gasketing, and Viton, or Buna-N Rubber lip type shaft seal.
2) Full face sheet gasketing, Red Silicone or White Nitrile.
3) Contiunuosly welded fan housings;
4) Gas-purged mechanical shaft seals in lieu of lip seals - for greater sealing capability at the shaft hole opening.
I order to achieve a proper sealing, the mechanical shaft seal should be purged. The recommended purge pressure is 2 to 5 PSI above the process gas pressure.
Lip seals are furnished with two seal elements, each with a stainless steel spring for maintaining surface contact. The seal assembly is lubricated with" never-seeze". Mechanical seals are double or triple carbon ring seals mounted in a carbon steel housing. The seal housing is furnished with two purge ports.
To ensure proper fan sealing, Soap Bubble or Chalk / Kerosene tesing of the blower assembly is performed. This ensures that continuous weld has completely sealed the housing seams (liquid tight).
Northen Industrial Co. is a world wide distributor of industrial process ans OEM fans and blowers, as well as fan components; including high pressure blowers, high temperature fans, spark resistant and explosion proof ventilators, tubeaxial and vaneaxial high pressure ventilators. Northen Industrial also does existing fans and blowers repairs, re-build, as well as dynamical wheels balancing.
