The Twisted World Of Rotary Screws

Rotary-screw compressors are used when piston compressor power just won’t do. Jackhammers and construction machinery are prime examples of this.

Rotary-screws are first and foremost gas compressors. They use rotary-type positive displacement processes to produce compressed air. Pulsing or surging air is kept to a minimum by the sweeping motion of this compressor. Rotary screws are relatively small machines and due to their mechanism, emit little to no vibration. The power of these compressors varies with the size and function. The smallest ones are capable of operating at ten cubic feet per minute (CFM), while the industrial grade compressors can give off more than a two thousand CFM. Though that number is high enough to power large machines for construction, extremely high-powered machines (turbomachinery) such as jet engines need centrifugal compressors.

There are two types of rotary-screw machines. The first one is an oil-free rotary screw compressor, which is used for medical research and semiconductor manufacturing. There is absolutely no place for oil leakage in these processes. Oil-injected rotary-screw compressors are used almost everywhere else.

The drawback of this machine is leakage of oil and fluid into the rotary-screw chamber. The speed at which the screws rotate compensates for the leakage by making the compressor more effective, and the power output higher.

The Advantages Of Purchasing Factory Direct Equipment

Buying an equipment straight from the manufacturer has its upsides. Back in 2009, direct-to-consumer became the fastest growing online retail category because of its advantages. And consumers have a similar preference for factory direct equipment.

The commonly known advantage of choosing a machinery that was purchased directly from the manufacturer is the elimination of the middleman. Typically, any product coming out of the factory passes through more than one middleman, including sourcing agents, trade agents, import firms, wholesalers and distributors.

With everyone receiving a cut of the profits, the product becomes more expensive than it is supposed to be. Importing the final products or even raw materials can entail additional fees, such as import/export charges, transfer and inspection fees, and other surcharges.

It is not just in a financial sense that one can benefit from purchasing straight from the factory. By being in direct contact with the manufacturer, the quality of the product can be guaranteed, as every part of the manufacturing process – the raw materials, the production lines, the quality assurance – involves transparency.

Customer satisfaction is also increased because faster and better customer service comes with the purchase. There is immediate and efficient communication as there is complete accountability on the part of the manufacturer. Customer service is premium with factor direct purchases.
