OIL-FREE SCREW COMPRESSORS

WHY DO YOU NEED OIL-FREE COMPRESSED AIR?     NO RISK OF CONTAMINATION LESS ENVIRONMENTAL IMPACT LOWER MAINTENANCE COSTS LOWER ENERGY COSTS The quality of compressed air can be divided into many levels. Compressing suction dust, moisture, oil, and oil vapors in the compressor can have the following consequences: – loss of production, – scrapping and recalling products, – decline of the brand's reputation, and – decline in consumer interest in your product. Regardless of the type of your line of business, your need for quality compressed air can be complex, but providing a high level of...

During the production process, compressed air comes into contact with almost everything, including finished products. It is especially important to avoid contact with oil and oil vapours in the following industries: Medicine and pharmacy In medicine and pharmacy, the purity and quality of the final product is a key factor in the later effectiveness of the products. Many manufacturing processes require virtually zero tolerance for the content of impurities such as oil or moisture in compressed air. It is crucial to minimise the risk of contamination of the product or process. Food and...

SUPERIOR COMPONENTS INTEGRATED INTO ONE UNIT MA OF series compressors are produced with latest technologies and highest manufactural standards. MA OF series models Model Fixed speed Frequency speed control Water cooling Suction valve A hydraulic system is used instead of a pneumatic one to regulate the air intake. This prevents the need for periodic replacement of pneumatic components and reduces unnecessary congestion and maintenance costs. Surface treatment of screw elements Organic high temperature resin is thin, hard, antioxidant, and solid. The rotor surface is sandblasted for better...

Water cooling Venturi tube Efficient heat exchangers Air/water heat exchangers are available on the MA OF WC models, only water cooling is available on sizes MA OF 55 to 280. The use of air/water heat exchangers provides the option of using waste heat. The pipes are made of 304L SS stainless steel and nickel copper and are more resistant to corrosion. The pipe installation is easy to clean and replace. A venturi tube is installed at the outlet of the screw element to prevent pressure flow, flow pulsation, vibration, and high frequency noise. An efficient heat exchanger system with a...

SCREW ELEMENT WITH OIL-FREE DESIGN Lower energy consumption and longer service intervals LEADING TECHNOLOGY The two-stage air compression technology system includes two pairs of high-quality and highperformance GHH rotors that do not use oil to seal the gap between the screws, completely eliminating the presence of oil in the compressed air. The two-stage technology is much more stable and reliable than a single water-lubricated unit, and maintenance costs are low. TWO-STAGE COMPRESSION Two-stage compression with two screw blocks enables stable operation without deviations in air supply....

SURFACE TREATMENT OF SCREW ELEMENTS Special surface protection of screw elements provides excellent resistance to temperature changes and provides invaluable protection. Organic temperature resistant resin is thin, hard, antioxidant, and unbreakable. The surface of the rotor is sandblasted before application, which ensures better mechanical adhesion between the rough surface and the coating. Robotic coating ensures even application thickness. The super coating has many advantages: – exceptional compressed air quality, – longer service life of screw elements, – less production downtime, –...

COMPRESSOR OPERATING PRINCIPLE Air enters the compressor through a plate filter (12) mounted on the compressor housing and the suction filter (11), then enters the first stage screw element (2) via the suction valve (4), which is opened by means of a suction regulator (5). The inlet pressure of the second stage is shown on the manometer. After leaving the second stage screw element (3), the compressed air first flows through the Venturi pipe, non-return valve (15), and second stage air cooler (10), then through the air-water separator (20), and the condensate is automatically discharged via...
