B&D Water Injected Oil Free Rotary Screw Air Compressor FAQ

What is a B&D Water Injected Oil Free Rotary Screw Air Compressor? +

A B&D Water Injected Oil Free Rotary Screw Air Compressor is a type of air compressor that uses water instead of oil to lubricate, cool, and seal the compression chamber. This design ensures 100% oil-free air output, making it ideal for industries where air purity is critical, such as food processing or medical applications.

How does a water-injected oil-free compressor differ from a dry oil-free compressor? +

The main difference lies in the lubrication and cooling process. Water-injected oil-free compressors use water for lubrication, cooling, and noise reduction, offering clear air after purification. In contrast, dry oil-free compressors use no lubrication medium in the compression chamber, resulting in air that may contain dust and oil stains. Water-injected types generally have a simpler structure, lower vibration and noise levels, and longer durability compared to dry oil-free types.

What are the advantages of using a water-injected oil-free screw air compressor? +

The advantages include 100% oil-free air quality, ensuring no oil contamination in processes. They also feature lower operating temperatures (less than 55℃) due to water’s cooling effect, leading to enhanced durability and lower maintenance costs, as only air and water filter elements need replacement.

What is the typical maintenance required for a water-injected oil-free screw air compressor? +

Typical maintenance involves regularly checking and replacing air and water filter elements. Unlike dry oil-free compressors, which require more frequent replacement of spare parts and coatings, water-injected compressors have lower maintenance costs and simpler upkeep due to their design and operation mechanism.

What is the minimum order quantity (MOQ) for a B&D Water Injected Oil Free Rotary Screw Air Compressor? +

The minimum order quantity (MOQ) for a B&D Water Injected Oil Free Rotary Screw Air Compressor is 1 piece. This flexibility supports both retail and wholesale purchasing options.

What are the payment terms for purchasing a B&D Water Injected Oil Free Rotary Screw Air Compressor? +

The payment terms for purchasing a B&D Water Injected Oil Free Rotary Screw Air Compressor are either TT (Telegraphic Transfer) or LC (Letter of Credit). These options provide secure and versatile payment methods for buyers.

What is the lead time for delivery of a B&D Water Injected Oil Free Rotary Screw Air Compressor? +

The lead time for delivery ranges from 3 to 35 days, depending on the order’s specifics and customization requirements.

Are water-injected oil-free screw air compressors environmentally friendly? +

Yes, water-injected oil-free screw air compressors are environmentally friendly due to their 100% oil-free air output, reducing the risk of environmental contamination. Additionally, the use of water as a lubricant and coolant minimizes the need for chemical lubricants.

Can water-injected oil-free screw air compressors be used in high-temperature environments? +

While these compressors operate efficiently at lower temperatures (less than 55℃), their performance in high-temperature environments may require additional cooling measures to maintain optimal operation and prevent overheating.

What industries benefit most from using a B&D Water Injected Oil Free Rotary Screw Air Compressor? +

Industries that benefit most include those requiring high air purity levels, such as food processing, pharmaceuticals, electronics manufacturing, and medical applications. The oil-free air output ensures that products and processes are not contaminated by oil.
