CENTRIFUGAL FANS

THREE IMPELLER STYLES:

MODEL LPRT (Low Pressure, Radial Tipped)

• For low static pressure requirements up to 8” wc, volumes up to 76,000 cfm
• Wheel blades are forward curved radial tipped for higher efficiency
• Blades are designed with a strong, short load span to accommodate sudden volume fluctuations

MODEL LPBI (Low Pressure, Backward Inclined)

• For low static pressure requirements up to 8" wc, volumes up to 76,000 cfm
• Wheel blades are backward inclined to provide a non-overloading characteristic
• Blades are wide to provide the same static pressure and volume performance as model LPRT
• Backward inclined design causes horsepower to rise to peak efficiency as volume increases, after which   horsepower and pressure decrease as volume increases further, providing the non-overloading feature

MODEL HPRS (High Pressure, Radial Straight)

• For high static pressure requirements up to 28" wc, volumes up to 100,000 cfm
• Wheel blades are straight and held firmly in position by a center cone and a conical end ring to provide the strength   required for high pressure performance
• Straight blades have excellent self-cleaning characteristics
• May be used where dust or other solids are in the air stream
