AB Blower Co. has been developing 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.
AB Blower a lot of experince with gas-tight and zero-leakage construction on fans and blowers Scottie Upshall Womens Jersey , 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, NISCO 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).
NISCO Fan 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. AB Blower also does existing fans and blowers repairs, re-build, as well as dynamical wheels balancing.

BEIJING, Dec. 31 (Xinhua) -- China's manufacturing sector continued to expand in December, pointing to economic resilience in the country's factory sector.
The country's manufacturing purchasing managers' index (PMI) came in at 51.6 in December, slightly decelerating from 51.8 in November, according to National Bureau of Statistics (NBS) data released Sunday.
A reading above 50 indicates expansion, while below reflects contraction.
The index in December is on par with the annual average, pointing to a strong resilience in China's growth, according to NBS senior statistician Zhao Qinghe.
Sub-indices for production and new orders came in at 54 and 53.4, respectively, down from 54.3 and 53.6 last month, but well above the boom-bust line of 50.
However, the sub-index of raw material inventory stood at 48 in December, down 0.4 points from last month, indicating continuously decreasing raw material inventory in the manufacturing sector.
Meanwhile, the sub-index of supplier deliveries declined 0.2 points month on month to 49.3, showing a slower delivery by raw material suppliers.
The manufacturing sector employed less people as the sub-index of employment dropped 0.3 percentage points month on month to 48.5 in December.
"Factory employment continued to contract slightly -- a mismatch with expanding output that might reflect the advance of automation," according to Tom Orlik, Bloomberg chief Asia economist.
The country's manufacturing PMI has been in positive territory for 17 months in a row despite overall slower expansion this month.
The NBS data also showed that the country's non-manufacturing sector expanded faster in December, with non-manufacturing PMI coming in at 55 in December, up from 54.8 in November.
The service sector, which accounted for more than half of the country's gross domestic product, continued steady growth, with the sector's business activity index standing at 53.4 in December, well above the boom-bust line of 50,.
