Dear Sir,

I am writing in response to your inquiry and website visit today. Thank you for your interest in our computer cabinets. The computer cabinets are NEMA 12 rated and provide good dust protection with the exhaust cover and door seal. The cabinets have a dual purpose. First, they provide dust filtration and air purification. Second, today's computer cover cases are stronger than ever with a 314 Stainless Steel case and a  Black hair cell ABS sheeting front and Back. The door still has the original PLEXIGLAS ^TM clear transparent window. All of these feature are for impact protection, durability, and quite operation. 
     As you probably know, the airborne particles in a shop or office, such as dust or machine oil, act as insulators once inside your computer. What you may not know is that an unfiltered air supply is the main cause of overheating and slower processing speeds. Moreover, if you live near the ocean air bourne salt particles are often corrosive and cause serious computer damage, as does static. In all three cases, the periodic IT or MIS repair bills are costly a minimum of $400 and downtime is unavoidable without a protective enclosure.

 Our computer cabinet offers you a proven solution to this potentially costly problem:              

• 1) Reduces IT service bills and computer expenses
• 2) Increases the Life expectancy of your computer asset providing the lowest annual and monthly depreciation than all other computer cabinets and covers
• 3) Protects your computer manufacturer warrantee by eliminating the need to remove the case to clean a computer  

       This is best illustrated on by reviewing our calculation worksheet viewable on http://thompsonplasticvalley.com/id77.html What sets our computer cabinet apart from just another is the composite air filter system. It has the most efficient air filtration capturing 99% of dust particles 0.3-1.0 microns in diameter which no human can see and no metal mesh screen is going to catch. The main filter has a green colored  rubber gasket the pleated automotive air filter is compatible with your John Deere equipment and available in any automotive store for $6.66). This creates  a Vacuum seal filter holder when it is compressed in a slideable track in the side of the stainless steel  sheet metal case section. The Valley Plastics TM PC dust Cover has dual 4.625"fans in the CPU cases or covers and is an all positive air flow design.
 
    The air flows inward towards the CPU. The enclosure fans run continuously, but are available with variable speeds for quiter operation. The greater air pressure or flow inside the cabinet causes air to exhaust out the rear holes or mesh shown in the photos and patent application drawings. http://thompsonplastic.web.aplus.net/id31.html . These units are economically priced the largest all-in-one cover holsd the tower or desktop PC, the monitor, and the printer & keyboard for about $600 less than our competition. Air  air filter cost for the year is $6.66. The units will pay for themselves the day you recieve them in the peace of mind you will get and in less than 6 months assuming maintenance cleanup savings of $50 per month and a costly hard drive failure is prevented.

   Prevention of downtime over the 3 year life of the computer assets in your shop environment will fetch you a few hundred dollars when you sell the shop computers in 3 years and the money saved (after breakeven point) for a factory with 10 computers is $1200x10= $12,000 USD.
The computer cover is part of a new IT TREND. We also developed an electronic dust sensor (see video). In it a sensitive micro-switch activates a green light when conditions are normal and a red light when the air flow (positive pressure of the cooling air inside the enclosures air plenum) is too low. click here to play video
