NEW TEST FACILITYNew Test Facility,Second to None

The acoustic facility consists of a 40,000 ft3 reverberant room, and the airside test facility consists of a 170 ft2cross-section wind tunnel.

After 17 months of hard work, Energy Labs’ reverberant room is ready to operate

Spring 2002No. 001 Energy Labs Inc.A publication of

Energy Labs' new acoustical and air performancetest facility has been completed and is ready to operate.Construction of the 35,000 ft facility began in July of2000 and was completed in December of 2001. We arenow preparing for AMCA accreditation of the facilityunder their Standard 111 Laboratory RegistrationProgram. Once accreditation is complete, expected byearly April, we will be able to conduct and certify tests ofAir Handling units and components such as fans anddampers in accordance with AMCA Standards 210, 300and 320, as well as ARI260.

Our acoustic facility was designed by prominentWest Coast Acoustician Mark Schaffer, specifically fortesting Air Handling equipment. It consists of a 40,000ft reverberant room, which features non-rectilinearconcrete walls and roof surfaces. Air Handling units up toapproximately 40,000 CFM can be tested inside the reverberantroom for casing radiated and inlet or outlet sound power levels.Air Handling units up to approximately 80,000 CFM can be testedfor inlet or outlet sound power levels by ducting into thereverberant room.

Welcome to AIR TRENDS, Energy Labs' quarterly newsletter.We at Energy Labs felt we needed a forum to share

information about our company with our Rep Organization.It is our goal to issue a Newsletter every quarter. In each issue we

will keep you informed about market and sales issues, research anddevelopment, new products, Rep organization changes and a projectof the quarter. I have asked all departments to contribute to this

newsletter so you will be informed about majordevelopments in their group. Every quarter we willselect one of our highlight projects to write afeature story.

The largest laboratory space in the United States,approximately 250,000 square feet on six floors stands inBethesda, Maryland in Building 50 of the National Institute ofHealth (NIH).

The NIH Building 50 project or Louis Stokes Laboratoriesas it is now called after the Honorable Louis B. Stokes(retired Ohio congressman), received several awards forenergy efficiency. This building features four very large100% OSA Energy Labs, Inc. units with energy recovery

Last year we added an extra40,000 square feet to our plant, inwhich we have included a fan shopassembly area, fan inventory,machine shop, two cranes, a foambooth for base insulation, restrooms

and accessibility for incoming material.This space will allow us to incorporate a stand-alone

base department able to shear, notch and bend its own sheetmetal for the floor and cross members. The fan shop, with astart to finish layout, will reduce the material traveling timeconsiderably.

Also a full assembly line will be established, thisassembly line will have all of the required componentsavailable with a very short traveling distance through the plant.

Proper care of the bearingsused on our fans will help to

guarantee that the maximum life ofthe bearing is achieved withoutpremature failure. This care isnecessary for bearings on fansboth stored (idle) and in use.

STORAGE AND SHUT DOWN

� For fans in new units that are tobe stored for more than a onemonth period before installation,or for operating fans that will beshut down for more than a onemonth period, a program to rotateeach fan manually several timesat least once each month shouldbe initiated.

� The bearings should be lightlygreased while the bearings arebeing rotated. Light greasingmeans there should be a smallbead of grease extruded aroundthe bearing seal. You should wipeoff any existing grease before youre-grease. This will also reduceany slinging of excess greasearound the fan compartmentwhen the fan is started.

� To schedule and keep track of thisbearing maintenance program apermanent service log with the fanidentification, date when therotation/greasing is required, adate when the lubrication wasdone and a signature of who didthe work should be set up andkept in a convenient securelocation. The log should also listthe type of grease used.
