SECTION 7200 ENGINEERING SPECIFICATION: AIR STRIPPER BLOWER PART 1— GENERAL 1.1 1.1.1 1.2 1.2.1 SCOPE The manufacturer shall furnish a blower for use with a low profile, multitray Air Stripper. PROCESS DESCRIPTION The blower impeller, driven by the direct-coupled motor, pressurizes air and supplies it to the stripper with sufficient flow and pressure to generate a froth of bubbles in the water contained by up to six stripper trays. SUBMITTALS Manufacturer shall submit the following with the bid: Product data for selected model, including rated output capacity, electrical specifications, and warranty coverage. See Data Sheet for full specification.

PART 2 — PRODUCTS 2.1 2.1.1 GENERAL The blower shall be a direct drive pressure blower (scroll type or a direct drive regenerative type blower. See Data Sheet for model number. Equipment shall be supplied by QED Environmental Systems, Inc. and represented by ______________ or pre-approved equivalent. Blower design and performance shall meet requirements specified on the Data Sheet attached to this specification. EQUIPMENT DESIGN REQUIREMENTS-DIRECT DRIVE BLOWER Standard product design shall include one pressure blower with allwelded steel housing and aluminum wheel, with the following specifications:

2.2.1.1 Movement and AMCA 2.2.1.2 2.2.1.3 to overload 2.2.1.4 desired. 2.2.1.5 2.2.2
Blower shall be an industrial quality model rated for continuous duty, certified and licensed to bear the AMCA (Air Control Association, Inc.) Seal, in accordance with Publication 211. Blower shall be factory balanced and motor-coupled. Blower shall be supplied with an air flow throttle, factory installed preset to match stripper system requirements, and labeled indicate settings for clean operation, turn-up range, and conditions. Blower inlet shall be equipped with a 90 ° elbow serving as an inlet safety guard, ready for connection to an air inlet duct if Blower shall include a built-in water drain.
Standard product design shall include one industrial quality (such as Baldor, GE or preapproved equal) electric motor, with the following specifications: Blower-motor unit shall be a compact, direct-drive arrangement with the blower wheel mounted directly on motorshaft, to minimize the number of moving parts and for ease of maintenance. Motor must meet the system’s electrical voltage/phase and explosion-proof requirements (if applicable). See attached Sheet for specifications. Standard product design shall include outlet ducting to connect the outlet flange to the stripper inlet ducting. Duct size and design shall be sufficient to allow the blower to operate at full capacity. Duct design shall include a section routed high to prevent water from reaching the blower in the event of a system shutdown. Blower/motor unit shall be primed and painted. EQUIPMENT DESIGN REQUIREMENTS-REGENERATIVE BLOWER Standard product design shall include one regenerative blower with cast rather than fabricated aluminum impeller (for ruggedness), housing and cover, meeting the following specifications: Blower shall be an industrial quality model rated for continuous duty at the required workload.
2.2.2.2 Data 2.2.3 blower
Blower shall be factory balanced and motor-coupled. Blower shall be equipped with a Teflon shaft seal, final assembly leak tested to less than 1cc/sec @ 3 psi. Blower shall be supplied with an air flow throttle, factory installed preset to match stripper system requirements, and labeled to indicate settings for clean operation, turn-up range, and overload conditions. Blower shall be equipped with an inlet filter and integral intake and exhaust mufflers, held in place with a screen (spring or wire holddown is not acceptable), to minimize operating noise levels. Inlet and outlet flanges shall be of cast iron; soft metals, such as aluminum are not allowed. Standard product design shall include one industrial quality UL and CSA approved electric motor, with the following specification: Blower-motor unit shall be a maintenance-free, compact directdrive arrangement. Motor must meet the system’s electrical voltage/phase and explosion-proof requirements (if applicable). See attached Data Sheet for specifications. Motor must be rated for continuous duty and carry full rated load at temperatures below insulation limits; motor ball bearings shall be double sealed with a rated life of not less than 20,000 hours continuous duty at the maximum rated blower load. Standard product design shall include outlet ducting to connect the outlet flange to the stripper inlet ducting. Duct size and design shall be sufficient to allow the blower to operate at full capacity. Duct design shall include a section routed high to prevent water from reaching the blower in the event of a system shutdown. Blower/motor unit shall be primed and painted. OPERATION AND PERFORMANCE PARAMETERS Blower shall be sized to allow turn-up to overcome fouling of the stripper, extending the time between cleanings. See Data Sheet for output curves.
