19 ACCESSORIES Fan Speed Control Cook s FSC is a variable speed controller which can offer excellent energy conservation and lower sound levels when percent of a direct drive fan operating capacity is not required. The FSC employs solid state circuitry for long life and dependability. The FSC is available only on 5V and 23V shaded pole or permanent split capacitor direct drive motors and is not available on 4 RPM and 725 RPM motors. The FSC is normally shipped loose for field installation. Optional pre-wiring is available. 5 AMP FSC AMP FSC Motors Direct Drive All direct drive motors are standard single phase 5-volt. Sizes 7 through are either shaded pole or permanent split capacitor type motors. Sizes 2 through 8 are either permanent split capacitor (75, 3, or 55 rpm motors) or split phase (4 or 725 rpm motors). FSC can only be used on either shaded pole or permanent split capacitor type motors. Optional motors: Two speed, single-phase open motors supplied as 725 RPM motors are 725/4, or 4 RPM motors are 4/86. Explosion proof motors are available for some units, contact factory for details. These optional motors cannot use an FSC. Belt Drive Single-phase motors: Open drip motors from /6 to -/. Two-speed, motors in 725/4RPM, from /6 to. TEFC and Class, Group D, explosion proof motors from /4 to. Three-phase motors: Three-phase ODP motors from /4 to. Two-speed, two winding motors in 725/4 RPM, from /3 to 5 HP. TEFC and Class, Group D, explosion proof motors from /4 to. Variable Frequency Drive (VFD) compatible motors are available, contact factory for details. All single-phase and three-phase, single speed, open drip motors listed in performance tables are shipped factory installed. Optional Coatings Lorenized is an electrostatically applied, baked polyester powder coating. Each component shall be subject to a five stage environmentally friendly wash system, followed by a minimum 2 mil thick baked powder finish. Coating must exceed, hour salt spray under ASTM B7 test method. Cook Epoxy Powder is an electrostatically applied, baked epoxy powder coating. Final coating thickness is mils. For outdoor applications an optional UV resistant topcoat is available to prevent cosmetic chalking of the coating. Cook Phenolic Epoxy Powder is an electrostatically applied, baked phenolic epoxy powder coating. Final coating thickness is 2-4 mils. For outdoor applications an optional UV resistant topcoat is required to prevent deterioration of the coating. Cook Easy Clean Powder is an electrostatically applied, baked modified epoxy silicone powder producing a high temperature "nonstick" coating. Final coating thickness is mils. Air Dry Phenolic (Heresite VR-54) is a conventional spray applied phenolic resin coating. Final coating thickness is 4-6 mils. For outdoor applications an optional UV resistant topcoat (Heresite UC-55) is required to prevent deterioration of the coating. Refer to the corrosion resistance guide in the Compute-A-Fan software for a listing of the coatings above and their resistance to a variety of chemicals. Additional special coatings are available. Cook Type A Construction Cook Type A construction option gives an AC unit superior corrosion resistance. The fan shaft and all steel fasteners exposed to the exterior environment are furnished with 34 stainless steel components. All other steel components exposed to the exterior environment are furnished with aluminum components. This option should not be interpreted to be an indication of spark resistance.

86 ACSC Power Ventilator for Smoke Control The UL Listing Power Ventilator for Smoke Control Systems is a test procedure and category which was initiated by Loren Cook Company and developed in a joint effort with UL in 99. Several different sources were used in the definition of the test procedure. These sources include UL Standards 75, 762, 793, Southern Building Code Congress International (SBCCI) Standard Fire Prevention Code/988, and Industrial Risk Insurers (IRI) Document E2. Requirements for UL Listing Power Ventilator for Smoke Control Systems The unit must withstand 5 F airstream temperature for a minimum of four hours (IRI) and withstand F for a minimum of 5 minutes (SBSCCI). The unit must be listed under UL 75. ACSC / ACSC-HP / ACSC-XP Smoke Control Ventilator Listed Power Ventilator for Smoke Control Systems. Upblast Centrifugal Roof Mounted Exhaust Ventilator listed by UL as Power Ventilator for Smoke Control Systems at 5 o F for 4 hours, and at, o F for 5 minutes. ACSC available in 4 belt drive sizes. Capacities range from 2 to 9,4 CFM, with static pressures from to -/2 inches. ACSC-HP available in belt drive high pressure sizes. Capacities range from 7 to 9,2 CFM, with static pressures from /4 to 2-/2 inches. ACSC-XP available in belt drive extended pressure sizes. Capacities range from 8 to, CFM, with static pressures from to 4-/2 inches. UL Power Ventilator for Smoke Control Typical Application Ambient temperature not to exceed 2 o F Airflow (Ducted or Non-Ducted) Roof 84

87 LORENIZED fan finish Durable protection, lasting beauty All steel fan and blower components receive COOK s LORENIZED coating as the factory standard. When this coating goes on, it stays on. It s the industry s most durable standard coating. It comes out sleek and smooth and it stays that way. COOK s LORENIZED coating withstands the elements and provides durable protection and lasting beauty. The COOK Powder Coating Process Environmentally friendly The entire procedure occurs within a self-contained, automated system. Water used in the pretreatment recirculates and is neutralized before its release from the system. Excess powder is captured and recycled. No solvents are utilized so there are no polluting fumes or paint vapors to escape. There is virtually nothing in the entire process to adversely effect our environment. Cook Express A complete, up-to-date listing of all products available for custom assembly and next day shipping! Specified fan RPM s for belt driven units are factory set and all fans are shipped in tough, Transit Tested Packaging. Steel components go through a five stage pretreatment process before the powder is applied. They are washed and treated until all surfaces are perfectly clean, chemically prepared and electrostatically charged - ready to bond with the powder. This insures excellent coating adhesion, uniformity and consistant edge coverage. COOK s Digital Media Center......your source for product selection information! An automated system of sprayers applies the powder that chemically bonds to the prepared surface. Components are then cured in a 4 o F oven. This process creates adhesion, durability and a smoothness of coating not possible with conventional liquid paints. Other Available Coatings... Where particularly harsh environmental conditions require exceptional chemical resistance, these optional coatings may apply: Cook Epoxy Powder Cook Phenolic Epoxy Powder Cook Easy Clean Powder Cook High Temp Air Dry Phenolic (Heresite VR-54) Compute-A-Fan - for Windows is an easy to use fan selection program. Simply select a fan type, enter air flow and pressure in either metric or English units and all valid selections are displayed in a grid with budget pricing, estimated energy costs and payback. FanDrafter - is a collection of CAD drawing files (templates) of every Cook product drawn to scale in every size. Each drawing includes multiple views drawn full scale for a particular size. Electronic Publications - view product s, Installation, Operation & Maintenance manu als, Submittals and Typical Specifications. ISO 9 Certification Video - learn more about Cook s ISO 9 compliant quality system and quality certification. Airflow & System Effect Video - which illustrates important design issues regarding airflow and system effect.
