2 I PRSSUR LOWRS OVRVIW RO I RS Model RO and RS fans from Twin ity an & lower are specifically designed to provide low flow and high static pressure for industrial applications. The wheel design offers maximum strength and reliability. vailable in three (3) designs, the RO and RS allow for flexibility in selection depending upon the application. The design allows for a low flow reducing or even eliminating the requirement for recirculating or exhausting excess air. esign 1 has the lowest flow, followed by esign 2, and then esign 3.

3 RIV RRNMNTS rrangement 4 rrangement 4 is a direct drive fan with the wheel mounted directly on the motor shaft. This drive arrangement is the most compact and requires minimum maintenance and service. Standard rrangement 4 fans are suitable to 0 operating temperature. Maximum rotational speeds for arrangement 4 fans can be found on page 6. rrangement 8 rrangement 8 is a direct-drive unit with the wheel mounted on a separate fan shaft that is mounted to the fan pedestal with pillow block bearings (minimum L-,000 hours). The fan shaft is connected to the motor shaft with a flexible coupling. rrangement 8 blowers offer the ability to remove the motor for service without disturbing the fan assembly. rrangement 8 units are limited to 0 as standard. igh temperature packages are available for up to 600. Maximum rotational speeds for arrangement 8 fans can be found on page 6. rrangement 1 V-belt drive fans are available in arrangement 1 only. rrangement 1 units are limited to 0 as standard. igh temperature packages are available for up to 600. Maximum rotational speeds for arrangement 1 fans can be found on page 6. rrangement 1 WL SIN Wheel onstruction ll wheels are constructed to insure maximum strength and reliability. Wheels are statically and dynamically balanced on the most modern electronic equipment. very blower unit is given a final running mechanical test and trim balance before shipment. RO (Radial, Open Wheel) The RO wheel features a full back plate with radial blades that are constructed of steel. The RO is ideal for light particulate- or vapor-laden gas streams. The RO is only available in esigns 1 and 3. RS (Radial, Shrouded Wheel) The RS wheel features a full backplate and a fully shrouded frontplate. The RS design develops the most pressure for a given speed and offers the highest efficiency. The RS is available in esigns 1, 2, and 3. RO Wheel RS Wheel 3

They consist of a ceramic felt element in compression to minimize air leakage. This shaft seal does not make the fan gas tight. onsult factory for other available shaft seal options. langed Inlet The standard flanged inlet enables attachment of rigid pipe connections on the blower inlet. The flange is drilled to match 1/1# NSI pipe flange. langed Outlet The standard flanged outlet enables attachment of rigid pipe connections on the blower outlet. The flange is drilled to match 1/1# NSI pipe flange. ousing rain with Plug The standard housing drain consists of a 3/4" NPT halfcoupling welded to the fan housing in the lowest point allowing for drainage of condensate from fan housing. plug is included. SSORIS Inlet ell Installations with an open inlet, an inlet bell (venturi) is required to achieve the catalog performance. Inlet screen is available. elt uard n OS belt guard protects personnel from the moving drive parts. quick access guard is available. ccess Port Shaft and earing uard Outlet last ate manually actuated blast gate for mounting to the fan outlet flange allows for controlling flow to full shutoff. vailable for automatic control.

Shaft and earing uard Solid sheet metal guards cover shaft and bearings and come with extended lube lines to a common point out either side of the guard. guard spanning the shaft between the bearings is also available to provide easy access to bearings for lubrication and vibration monitoring. Optional painted safety yellow is available. Split ousing ll sizes are designed to permit wheel removal through the fan inlet. Sizes and larger are available with a horizontal, pie-shaped, or 3-way split housing, which allows removal of the wheel and shaft without disconnecting ductwork. 4 TWIN ITY N - TLO 10

5 OPTIONL ONSTRUTION Spark Resistant onstruction an applications may involve the handling of fumes or vapors. Such applications require careful consideration by the system designer to insure the safe handling of such gases. Twin ity an & lower offers the following classifications of spark resistant construction per M Standard It is the specifier s or the user s responsibility to specify the type of spark resistant construction with full recognition of the potential hazards and the degree of protection required. onstruction Type : ll parts of the fan in contact with the airstream must be made of nonferrous material usually an aluminum and limited to 0. Type : The fan shall have a nonferrous wheel and nonferrous rub ring about the opening through which the shaft passes usually an aluminum wheel and rub ring and limited to 0. Type : onsult factory. Nominally Leak-Tight onstruction When leakage is a concern, nominally leak-tight construction should be considered. or fans with positive pressure conditions at the inlet, please consult the factory. Nominally leak-tight is available for arrangement 1 and arrangement 8 fans. onstruction modifications may include, but are not limited to (depending on the application) continuously welded inlet and outlet flanges, closecentered bolts on all flanges, access doors, cover plates, una-n rubber shaft seal as standard (other mechanical seals available). earing with Shaft ooler & Shaft Seal Table 1: erating actors for Safe Wheel Speed Temperature ( ) lloy Steel Stainless Steel igh Temperature Package an Standard designs are suitable to 0 for rr. 4 and 0 for rr. 1 and rr. 8 fans.

7 N SLTION The performance curves in this catalog are based on fans handling standard air at a density of 0.07 pounds per cubic foot. This is equivalent to air at 70 at sea level (29.92" g. barometric pressure). Thus, when specified performance is at a density other than standard, it must be converted to the equivalent standard conditions before entering the performance curves. The equivalent standard conditions can be calculated by using the Twin ity an & lower an Selector Program. The fan selection curves on the following pages show performance at nominal diameter as well as 80% and 0% of nominal. Variation in wheel width is not available. Performance curves utilize a logarithmic scale for the axes.
