EXPENDABLE MATERIAL SPECIFICATIONS FOR MAINTENANCES

1. GLASS FIBER AIR FILTERS FOR AIR HANDLING UNIT (AHU)

LOCAL MATERIAL: Interwoven from long, fine-spun fibers, these filters provide a large dust-catching surface with maximum ventilating efficiency. The resilient, flexible medium insures minimum restriction - no glass splinters or greasy mess. Filters are treated with dust catching adhesive. Dust penetrates the filter and builds up uniformly from inside, not just on the face. Filters have a heavy-duty, one-piece frame construction. The rugged metal facing on both sides is securely fastened to the frame by continuous bonding. UL listed as Class II fire rating or approved equal. Clean filter resistance is 0.070 inches water gage for 1” thick and 0.080 inches water gage for 2” thick.

21. EXTENDED SURFACE AIR FILTERS FOR COMPUTER ROOM AIR CONDITIONER (AC) - LOCAL

MATERIAL: Disposable extended surface filters are fully interchangeable in most built up filter banks, central air handling stations, and side access filter housings. These filters feature an average efficiency of 25% - 30% and an average resistance, which exceeds 90% when tested in accordance with ASHRAE 52-76 standards. The double wall frame of heavy-duty beverage board is treated for moisture resistance and has integral diagonal support members. Filter media of non-woven reinforce cotton fiber is supported by a metal grid. UL Approved as a Class II air filter unit tested per UL Standard 900 or approved equal.

3. PERMANENT WASHABLE AIR FILTER FOR FAN COIL UNIT (FCU): Rigid filters fit everywhere and are easily cut to the exact size with just a pair of scissors. Filters feature an extremely high dust holding capacity and low resistance to air flow. Filters are made of natural hairs that are cured, treated and permanently coated with a plastic and neoprene compound. This coating creates an electrostatic attraction for dust. Filters are sanitized and resist odors, mold, and mildew.

42. LITHIUM BASE GREASE: National Lubricating Grease Institute (NLGI) No. 2 (Media Soft) is water repellent, and works well under extreme pressures. Working temperature range is 10 degrees F to 400 degrees F.

53. COIL CLEANER: Coil cleaners shall be not be harmful to people and environment-friendly. The cleaners to be used shall be commercially acceptable and accepted either by the recognized organization of Korea government or USDA. Submission of MSDS and approval from the COR shall be accomplished before use. Recommend to separately use the cleaners, indoor and outdoor purpose.
