QZ

QZ

Radial Bladed Centrifugal Fans

The QZ Range of industrial centrifugal fan is ideal for high pressure applications ranging from 85m 3 /hr to 6000m 3 /hr. The QZ centrifugal fan can be supplied as both direct drive and belt driven. Impellers are radial bladed and can handle light dust loadings. The QZ Industrial fan can be supplied with thickened casings to achieve lower noise levels. The QZ can also be designed and manufactured to ATEX certified specifications.

GXZ

Gas Exhauster Fans

In the early days of landfill gas extraction our customers adopted the well proven Fans & Blowers GB gas booster fan. Since those early years we have worked closely with our customers to evolve the GB design into a special purpose gas exhausting fan, the GXZ, designed for the arduous requirements of landfill gas extraction. By its nature, landfill gas compared to natural gas can contain many various contaminates including solids, H2S and water vapour. The boosters are also frequently exposed to atmospheric pollution. The GXZ exhauster is therefore of robust construction, with drain plug, inlet & outlet flanges to PN16 (others available) fully welded gas tight casing. Casing, impeller, seal housing and motor pedestal all 304 stainless steel for maximum protection against internal and external corrosion. The gas seal at the point of shaft entry to the fan casing is the well proven Fans & Blowers double Viton lip seal, grease packed for lubrication and maximum sealing efficiency. Grease nipples are fitted to enable the correct re-greasing schedule to be carried out. Fans & Blowers gas tight industrial fans are designed, manufactured, tested & certified to BS8487:2007 for the Design & Construction of Gas boosters. Motors are IP55 enclosure metric frame with thermistors, hazardous area classification to suit Zoning. Special shaft extension to accommodate gas seal if overhung design. Most of the GXZ fans we supply are required for hazardous areas and as such will be designed, manufactured, tested & certified in compliance with ATEX Directive 94/9/EC for use in either Zone 1, Cat.2G or Zone 2, Cat.3G.   Zone 1 certification also includes for technical file lodged with SIRA Test & Certification Ltd, File ref. 04-ATEX 334. Zone 1 fans will have Eexd motors, Zone 2 Eexn. (Zone 2 long shaft motors are normally kept in Fans & Blowers stock) Our ATEX certified fans can also be designed for Zone 21 & 22, Cat. 2D & 3D (dust) and different zones inside & outside fan casing. Anti-vibration mounts are available as are flexible inlet/outlet connections, these being of the stainless steel convoluted / braided bellows type.

BSZ

Backward Bladed Centrifugal Fans

The BSZ industrial centrifugal fan range incorporates four standard widths; 100%, 75%, 60% and 40%. These widths combined with impeller diameters of 400mm to 1200mm give a volume range of approximately 1000 ft 3 /min (1700 m 3 /hr) to 60000 ft 3 /min (100,000 m 3 /hr) and pressure up to 30”swg (762mmwg). The flat backward inclined blade design of the impeller enables the BSZ centrifugal fans to handle air with a light dust loading as well as standard air and hot gas applications to approximately 800°C (1500°F)
QPZ

QPZ

Radial Bladed Centrifugal Fans

High pressure applications ranging from 85m 3 /hr to 6000m 3 /hr. The QPZ radial bladed industrial centrifugal Fans can be supplied as both direct drive and belt driven. Impellers are radial bladed and can handle light dust loadings.
BSNZ

BSNZ

Backward Bladed Centrifugal Fans

The BSNZ range of industrial centrifugal fans incorporate three widths as standard. These are 50%, 35% and 20%. Three widths give a range of 680m 3 /Hr to 100,000m 3 /Hr and pressures up to 70” WG and could be classified as a medium volume high pressure industrial centrifugal fan . The BSNZ can be designed and manufactured to ATEX Specification.
BCZ

BCZ

Backward Curved Centrifugal Fan

The BCZ Industrial Centrifugal Fan is ideally suited for medium volume high pressure applications but can also be used for low volume and medium pressure. Duties range from 850m 3 /Hr. Impellers are backward curved non-overloading and suitable for clean air applications only.
QPZ Kit

QPZ Kit

Radial Bladed Centrifugal Fan

Advantages of Customer Assembly Kits Particularly for countries outside of Europe, the QPZ kits if bought in reasonable quantities, provide lowest transport costs. Enables delivery within normal lead times as if manufactured locally. The QPZ kit fan can be customised to suit, assemblies, nameplates, paint, colour and local motor etc. The major centrifugal fan components are made from mild steel sheet pressings which can be nested together to minimise transport costs and storage space.
AXZ

AXZ

Axial Fans

Impellers can be precisely matched – 5, 6, 8, 10, 12 and 16 blade configurations are available and blade angles can be easily set to the optimum angle to give the right airflow with minimum power consumption.
