MULTIBLADE FANS

The MULTIBLADE "squirrel cage" type "M" fans are usually specified for large volumes of flow against low to medium static pressures. There are several variations used for blade configuration; radial blower blades, backwardly inclined blades, and forward curved fan blades. We use the forward curved blades as they deliver the same volume of air, at reduced RPM, than the other versions. The reduced RPM is important as this yields lower stresses in the wheel allowing higher temperatures to be used for the air voluem specified. This series of fans has been developed and refined over the lifetime of the company and is suitable for continuous heavy-duty applications involving high temperatures with capabilities up to 1780 degrees F. We offer the multiblade in many configurations of housing fans and cartridges which match your requirements. The MULTIBLADE fan is the most common type used in the heat treating industry, however if there is dust in the air stream that could build up, our Radial Blade Fan should be used.

RADIAL BLADE FANS

The RADIAL BLADE, "paddle wheel" type "P" fans are usually specified for medium volumes of flow against medium to large static pressures. The "paddle wheel" is considered a self cleaning type of fan wheel. It may be used where there are various materials or dust in the air stream. This series of fans has been developed and refined over the lifetime of the company. Due to its rugged construction and structural integrity, it is suitable for continuous heavy duty applications involving high temperatures to 2200 degrees F. depending on fan wheel speed. We offer the radial blade in many configuerations of housing fans and cartridges which will match your requirements. 

AXIAL BLADE FANS

The AXIAL BLADE fans are usually specified for very large volumes of flow against low static pressures. The axial fan is defined as a unit where the air flows through the blades and is essentially parallel to the shaft mounting. We use several variations of fan blade configurations within our catalog. These consist of a radial curved, radially convoluted curve, radial inverse curve, and propeller type. This series of fans has been developed and refined over the lifetime of the company, and is suitable for continuous heavy duty applications involving high temperatures with capabilities up to 2200 degrees F. We offer the axial blade in various configurations of cartridges and cartridges with shrouds. The AXIAL BLADE fan is the most common type used in the aluminum annealing industry.

Type "T"
Pressure Blowers

The "T" type blower has been developed for continous heavy duty industrial applications requiring constant air pressures at varying air volumes. Type "T" Blowers are dependable and are well suited for clean air applications such as combustion air, cooling, drying, gas boosters, etc. The standard line has capactities from 280 CFM to 3750 CFM, and pressures to 32 ounces. These blowers are available in arrangement 4 for operation up to 180 degress F., and other arrangements to 600 degrees F. Features include rotatable and reversable housings, inlet venturi and outlets to fit American standard class 125 pipe flanges. A variety of accessories are available including air intake filters, silencers, blast gates and shaft seals. 

 WIDE RANGE OF SIZES
43 different sizes: 1 1/2" thru 50 H.P. 
Variety of housing designs, wheel diameters and outlet diameters result in a wide range of blower selection. 

 DESIGNED FOR CONTINOUS DUTY IN HIGH PRESSURE APPLICATIONS

Construction Features

WHEEL
Heavy Duty -- constructed of high strength aluminum with riveted connections. Blades are also tack welded to side plates, reducing rivet wear. Taper lock hub makes wheel easily removable. Aluminum construction is standard for operation up to 180 degrees F. Steel and Stainless Steel are also available. Wheel is staically and dynamically balanced to assure smooth operation. NOTE: Fan wheel is suitable for handling clean air only.

HEAVY-DUTY HOUSINGS
All welded, heavy-duty steel housings with thick side plates on both sides of housing enable housing to be field rotated at 22 1/2 degree increments to suit most required discharge positions. Standard fans are supplied with gasket between housing and side plates. Housings are reversible for required rotation. For gas tight construction see "Modifications." 

 DIRECT DRIVE ARRANGEMENT
Wheel is mounted directly on motor shaft. Maximum operating temperature is 180 degrees F. in arrangement 4. 

Modifications

Accessories

SHAFT SEAL
Radial Lip Fan Seals for use up to 225 degrees F. Assembly mounts against housing and is furnished with grease fittings. Note: Shaft seals do not make fan gas tight. 

 INTAKE AIR FILTER
Heavy duty dry type pleated media filters elements. Elements are reusable and and can be cleaned with commpressed air or by washing. Note: fan wheel is suitable for handling clean air only. 

SHAFT COOLER
Of high thermal conductivity and is split for easy installation or removal. Is used only on Arrangement 1, 8 and 9 fans at temperatures 201 to 600 degrees F. 

 BLAST GATE
Is of all-welded steel construction. Flanged at both ends to 125# piping standards and bolts to standard discharge. Has locking device to permit permanent fan damper position 

SILENCER
For effective silencing. Straight through, annular absorption type. Offers high degree of silencing -20-30 dB average attenuation. Low pressure drop silencers are available flanged on one or both ends. 

Type "PF" Pressure Blowers

The "PF" Pressure Blowers are single stage blowers for applications requiring high to moderate volumes at relatively high pressures. The open type impellers are of welded construction, and statically and dynamically balanced to assure smooth operation. The housings are of heavy welded plate with suitable bracing to withstand high pressures. Typical applications are cooling, drying, exhausting, gas boosters and ejector venturi. The "PF" pressure blowers are available for corrosive or elevated temperature applications. 

 "PF" Blowers have been developed for heavy industrial uses requiring proven performance and reliability in moderate to high air volumes at relatively high pressure applications. Type "PF" Blowers are designed for capacities from 1500 CFM to 20000CFM and pressures to 62" SP. Units are available in arrangements 1 and 8 for operations up to 1260 degrees F. Features include high-efficiency wheels constructed of various alloys, heavy-duty blower housings and air or water cooled bearings. Single wall uninsulated housings are standard, double wall insulated housing are available. Direct driven or V-belt driven fans are available. 

Backward Inclined Fans

Kaybee Heat Resistant, Sealed Motors

The Problem:

Application of rotational power to fans, compressors, gas pumps, mixers and other equipment operation under high temperatures has always been a presented problems. Especially in troublesome are applications invovling the handling of high temperature gases under sealed-in conditions. Bearing, seal and lubrication failures due to heat conducted through the shaft, shaft bending and general overheating of the entire drive unit due to inadequate air cooling are examples of the difficulties encountered. 

The Solution:

The K-B HEAT RESISTANT, SEALED MOTOR was developed as a direct drive unit, which copes successfully with shaft temperatures up to 2100 degrees F. under pressure, vacuum and high ambient temperature conditions. The unit is ideally suited to such metallurgical applications as carburizing, nitriding, cyanding, clean annealing and vacuum heat treating, which require both high temperature and gas tight sealing.
