Do you realize the fan that keeps your computer running cool, also brings in dirt, dust, smoke and hair, etc? While it is blowing warm air out the back of the case, it’s also drawing in dirty air through the front! This dirty air flows in through your floppy drive, CD-ROM drive and tape backup! No, this can’t be good for it.

Most PC computers (Mac’s too) have 2 internal cooling fans. One is in the power supply (that’s the one that exhausts the warm air out the back of the case), the other is attached to the main processor, the actual computer chip. These two fans are designed to provide the air cooling for the computer. However, while doing that, they also bring dust from the air into the computer case, leaving a coating of dirt on the motherboard, heat sinks and intel microprocessor itself. Why?  This is because they have a negative air flow with the fan drawing air in through side intake holes with the rear mounted fan blowing out of the case. This acts like a dirtbag creating a layer of insulation that eventually causes overheating. In machine shops metal dust or carbon dirt can short out the hard drive unit. So  the solution is the Valley Plastics TM PC Computer Cover which creates a shop shield against dust in the workplace and an antistatic shield in the home. How by using positive air flow or displacement? This means the air filter is in front of the intake fan which blows into and through the NEMA enclosure and exhausts out the holes instead of the reverse.

Positive displacement

The concept is simple to understand for anyone who has ever changed the radiator fluid on a car. If you stick the water hose into the top of the radiator after removing the cap and turn on the water you can positively displace the radiator fluid inside of the car radiator. Still you can use the drain plug but to flush out the radiator this method works well. But let me tell you the story on the Rolls Royce the only thing you can do is change the radiator fluid my dad did not flush out the radiator and just capped off the fluid levels and rusted it out. So positive displacement can save money in the long run even on the most expensive cars and air flow can be thought of as a fluid dynamics problem as well.

So what type of damage can these dirt particles and objects do to the PC computer? This causes dirt to be constantly flow and collect in the hard drives, and eventually it will start to clog them up once a layer of insulation is thick enough. Initially you will get READ/WRITE errors (won’t save your work), and eventually they will stop functioning. The real danger is that these drives usually perform the backups for your computer system and that vital code or information is directly affected resulting in lost data. This loss is often permanent with no solution or means for recovery. Therefore, the trend today in the IT and MIS technology field is towards solving the problem via prevention with a protective dust enclosure like the Valley Plastic Tm PC Computer Dust Cover.

Over time, your internal components (motherboard, chips, cards, hard drives etc) will have a layer of dust covering them causing them to overheat. The fan that is attached to your main computer chip gets clogged too, causing it to fail. When the fan quits, the chip overheats and your computer starts behaving erratically. The symptoms are slow performance, lockups and eventual shut-downs.

Solution!
The Valley Plastics Tm PC Dust Cover an industrial computer cabinet is the solution for this problem. It is designed to protect your computer and its components (and invaluable data!). The Valley Plastics TM PC Computer Dust Covers are sealed computer cabinets with an industrial axial tube type fan to keep a constant supply of cool, clean air inside. A replaceable filter helps to keep the foreign particles out of your computer and the positive air flow

Tough!
Made from 2 layers of Kevlar reinforced Plastic, the Valley Plastics TM PC Computer Cover is cabable of withstanding over 100 thousand pounds of impact over 6 times the strength of steel cabinets. The Kevlar door sections has two layers of Kevlar  192 cubic inches and will withstand anything but armor piercing bullets. The the bottom and tops walls have 192 cubic inces of Kevlar. The side walls each have 192 cubic inces of Kevlar. The seams of the outer walls are reinforced with unidirectional 3 k carbon fiber, and there is an inner wall section screwed to  ½ inch thick plastic support colums which are that are cemented to the outer walls.

Security!
With the lockable door, our enclosures can also be beneficial wherever access to a computer needs to be controlled. Ideal for computer servers where critical data needs to be protected!
