Introduction

This catalog features Fiberglass Reinforced Plastic Centrifugal Fan,

FTF models, which are suitable for use in the chemical, metal,

wastewater, semiconductor, pharmaceutical, pulp and paper, and

fertilizer industries. Our unique backward curved impeller leads the

industry in performance and sound characteristics. With over 60

years of manufacturing corrosion resistant products, we have

experience and technology to provide solutions.

ConstructionFeaturesWheel

The FTF wheel is a backward curved design, innovated with Computational

Fluid Dynamic (CFD) analysis. The FTF wheel is able to flow corrosive gas

efficiently with low noise characteristics. It consists of vinyl ester resin and is

manufactured with our own unique methods, providing high efficiency and

durability. Every impeller is molded with an attached shaft sleeve and back

vanes to create suction through the shaft hole and prevent a leak. All of the

impellers are statically and dynamically balanced in accordance with G6.3

per ANSI S2.19 / ISO1940.

Housing

The housing of FTF models 153 – 403 consists of vinyl ester resin. The

housing is designed to be aerodynamically efficient. Resin transfer molding

(RTM) allows us to manufacture high quality competitive products. These

models come with round suction and discharge flanges that increase durability.

The housing of FTF models 503 – 1203 consists of

polyester resin. This material is easy to form and

ideal for complex designs. It comes with round

suction and rectangular discharge flanges, and is

manufactured using the hand layup method.

All of housing are coated with a UV resistant coating.

Oil Lubricated Bearing and Shaft

1) NON-CONTACT SEAL

The oil bath unit has a non-contact seal to prevent an oil

leakage. It does not require any wear and tear parts, and

that will reduce maintenance duties.

2) OIL LEVEL INDICATOR

The oil bath comes with an oil indicator which shows how

much oil is left in the bath unit.

3) SELF-ALIGNMENT

The oil bath system is designed to keep the bearings in a

fixed and aligned position. This enables to eliminate the

process of bearing alignment.

4) GAS SEPARATE SEAL PLATE

The seal plate prevents gas from entering the oil bath

system and damaging the bearings. .

5) OIL CAP

The oil bath system comes with an oil cap. It has an air

ventilation hall to prevent the oil in the bath from leaking

through out of the shaft holes.

6) OIL DRAIN

The bath system also has a drain port for easy maintenance.

This bearing system uses oil for lubricant. It enables the

blower to run at over 5000 rpm and provides an excellent

smooth lubricated performance. The bearings are selected

minimum average bearing life (AFBMA L-10) in excess of

30,000 hours at the maximum fan RPM.

Every consideration was thought of when designing the

shaft system. The tip of the shaft is encapsulated in FRP

and prevents corrosion from the gas stream. Oil vapors coat

and protect the shaft inside of the oil bath system. As a

precaution, there is an epoxy coating applied to the exposed

parts of the shaft. The shaft material is carbon steel / ASTM

A194 Grade 2H. SS304 and 316 options are available.

Belt Guard The standard OSHA belt guard material is FRP, and comes

with an inspection window. Carbon steel, SS304, SS316

material guards are available as options.

Inspection Port

and Access Door Gasketed inspection ports and rectangular access

doors are available in several sizes for wheel

inspection or maintenance.

Duct ConnectionsThe outlet and inlet flanges are standard. See the

drawings for the detailed flange sizes. Undrilled flanges

and companion flanges are available to connect user’s

duct for easy installation.

FRP VENTILATION HOOD

FRP SILENCER

FRP SilencerThe silencers are mounted on the blower’s outlet

or inlet to reduce the duct noise by 15 – 25dB(A).

Sound enclosureSound enclosures decrease radiant

noise levels generated from the blower

and motor by 19 to 23 dB(A).

Weather Cover

Weather covers are available

for extra motor protection.

DrainPlugged and flanged drains are

available. Both have an option for

a PVC ball valve.

OptionalConstructionGraphite Impregnation

Graphite impregnation is available for spark resistant construction.

The gas-stream surfaces are grounded to the fan base.

Special materials

Several types of FRP constructions are available for high temperature and

severe gas conditions such as Chromic acids, Bleaches, and Hydrofluoric Acid.

Fire retardant brominated vinyl ester resin

Brominated vinyl ester resin is available upon requests. This will meet ASTM

E84 Class l flame 0-25 flame spread.

Synthetic Veil

Synthetic veil is available to protect air stream surfaces from severe

corrosive conditions.

ASTM D4167 Construction

Fan can be constructed to meet ASTM D4167 as an option.

Seal Plate TypeA polyethylene plate is the most basic seal type used for

protection of shaft and bearings. This plate will block the gas

from coming out of the shaft hole and prevent corrosion. Back

vanes on the impeller create suction pressure through the shaft

opening to prevent a leakage. If the blower is pushing more

than 65 % of total pressure, we recommend a different seal

type. PTFE seal plate is available.

Labyrinth SealA labyrinth seal comes with three seal plates for additional

protection. This type of seal is efficient and easy to maintain.

Back vanes on the impeller create suction pressure through

the shaft opening to prevent a leakage. If the blower is pushing

more than 65 % of total pressure, we recommend a different

seal type. PTFE seal plate is available.

Packing Seal Type

This option is deal for applications when discharge pressure

is high and used under severe conditions. This requires

a water supply to lubricate the gaskets and periodical

maintenance for better sealing. Mechanical seal options are

also available upon requests.

Water Seal TypeThis option is ideal for applications when discharge

pressure is high and used under severe conditions. This

seal requires a water supply to create a liquid membrane,

preventing a leak. Water seals do not have direct contact

with any moving parts, and require less maintenance.

Performance forFTF ModelsPerformance tables are developed using standard air which is 70°F at 29.92” atmospheric pressure (at sea level) and 0.0749 lbs.

If capacities at conditions other than those rates, correction factors must be applied to static pressure and BHP

STEP 1. When a fan runs at conditions other than ambient conditions, the correction factors in TABLE 1 and TABLE2 will be applied to correct

static pressure and horsepower

STEP 2. Choose size, rpm and BHP of fan from the fan performance tables.

STEP 3. Check the maximum safe speed of the fan shown in TABLE3

STEP 4. Apply temperature maximum safe speed factors show in TABLE4 to maximum safe speed of fan from STEP 3 to determine new

maximum safe speed.

STEP 5. Determine actual performance by dividing static pressure and BHP corrected from step 2 by the correction factor in STEP 1.
