Used Kaishan 15 hp rotary screw compressor

The Kaishan KRST-15 is a 15-horsepower, belt-driven rotary screw air compressor built on a horizontal air receiver tank (typically 120 gallons) for shops, maintenance departments, and light industrial facilities.

General Overview & Features

• Type: Single-stage, belt-driven rotary screw air compressor
• Air End: SKK series air end with an asymmetric 5/6 rotor profile
• Drive System: Belt drive with automatic tensioning designed to reduce energy loss
• Components: Includes a laminar flow inlet valve, an integrated aftercooler, 316 stainless steel control tubing, and a sound-attenuating enclosure.

Key Specifications (Varies by Voltage & Pressure Configuration)

• Horsepower: 15 HP
• Air Receiver Tank: 120-gallon horizontal tank (standard on US tank-mount models)
• Working/Max Pressure: 115 PSI to 150 PSI (depending on the exact sub-model, e.g., 115 PSIG or 125 PSIG)
• Capacity (CFM): Around 52 to 62 CFM depending on pressure rating (e.g., ~60–62 CFM at 90–115 PSI, or ~52 CFM at 150 PSI)
• Voltage 460V 3-phase power configurations
• Noise Level: Approximately 70 to 71 dB
• Unit Weight: Approximately 1,056 lbs

This unit also includes the Kaishan DRS060-1JT air dryer. The Kaishan DRS060-1 JT is a refrigerated compressed air dryer (from the DRS series) often integrated into or paired with industrial rotary screw compressor systems, such as tank-mounted Kaishan setups. It cools compressed air to condense and remove water vapor, preventing moisture damage in pneumatic tools and factory lines.

Key Specifications (Kaishan DRS 60 / DRS060 Series)

• Nominal Flow Capacity: 60 SCFM (approx. 102 m³/h)
• Dryer Type: Refrigerated compressed air dryer
