HF THERMOPLASTIC CENTRIFUGAL FANS
Fabco’s HF thermoplastic radial fans are designed specifi cally for exhausting aggressive,
low-aerosol gases, explosive atmosphere and ultra-clean air. The HF fan is
resistant to attack from most chemicals and as such ideally suited for applications in
chemical, pulp and paper, mining, plating, anodizing, fertilizer, pharmaceutical, waste
water treatment facilities as well as educational and institutional labs. HF radial fans
will accommodate explosive atmospheres. Our product range includes more than
150 standard components which allows for the design and construction of numerous
versions of fans. Axial, radial, and radial roof fans are available with direct drive motors
for consistent and maintenance-free performance. The housing is fabricated from
rotationally moulded Polyethylene (PE’s) that is both fl ame retardant and UV inhibited.
Additional thermoplastic materials are available to suit most applications. A condensate
drain is provided at the bottom point of the fan housing. The housing is mounted within
a rigid hot dipped galvanized frame. All sizes are available in clockwise or counter
clockwise rotations as well as six standard discharge positions. Both inlet and outlet
diameters are the same sizes for ease of installation of adjacent duct work. In addition,
fans can be fi tted with optional inlet and outlet fl anges. The impeller is manufactured
of injection moulded fl ame retardant polypropylene (PPs), statically and dynamically
balanced and keyed to the motor shaft by means of a taper lock bushing. The impeller
can be removed without fi rst having to dismantle the housing. All fans are supplied
with high effi ciency TEFC direct drive motors. Explosion and mill & chemical
service rated motors are available upon request. Available accessories include vibration
isolators, fl exible vibration isolators, inlet/outlet fl anges, shaft seals, inspection
ports, weather covers, starter/disconnect switches, variable frequency drives. Fans are
available in sizes ranging from 6” to 20” diameter with a variety of motors up to 3600
rpm and 1/2 hp. These fans can accommodate fl ow rates of up to 88,000 cfm and static
pressure up to 12” W.G.
Benefi ts
• Fan sizes from 6” up to 20” can attain a maximum effi ciency of 81% at the operating point.
• Impellers are backward inclined providing the highest and quietest operation with non-overloading horsepower characteristic.
• HF series impellers are 20% larger than the former Oktavent models; providing higher air and pressure specifi cations.
• The rotationally moulded housing has greater structural integrity, impact strength, fl ame retardant and UV inhibited.
• Available in axial as well.
• Impeller has massive blades, which are not easily damaged should unforeseen objects enter the intake duct.
Construction Features
• Standard housing/impellers is made of premium quality fl ame retardant and UV inhibited polyethylene (PEs). PEs (polyethylene
fl ame retardant gas temperature range is -20°C up to 60°C. Housings are rotationally moulded with a condensate drain at its
lowest point.
• The fan housing exhaust outlet can be rotated in steps of 45° through 360°. Normal position is 360°.
• All thermoplastic impellers are injection moulded, statically and dynamically balanced.
• The impeller is a self-cleaning, backward curved radial tip design allowing for stability at high S.P. and at low to medium fl ow rates.
• Metal hub, shaft and stainless steel fasteners are encapsulated in plastic.
• All belt drives shall have both shaft and belt guards attached which conforms to OSHA standard.
• Inlet and outlet openings are the same diameter allowing for easy duct connections both to plastic and steel ducting.
• Base frame is constructed of welded steel, and hot dip galvanized with motor support plate.
• The impeller is secured directly on the motor shaft by means of a taper lock bushing, which allows the impeller to be removed
without fi rst having to dismantle the housing.
• All bearings are designed for a minimum L-10 life when rated at the fan’s maximum cataloged operating speed.
• Only premium high effi ciency TEFC motors, which conform to IEC/Nema standards, are used. Special motors are available on
request. Both the shaft and all supplementary hardware (nuts, bolts and washers) are 316 stainless steel.
• Air performance ratings are based on tests and procedures performed in accordance with AMCA publication 211.
