Product Description

Keep your facility operating reliably by sourcing an Oil Injected Screw Compressor for Plants directly from the DECHUAN supply chain. It features high-load gear transmission and an optimized rotor layout, reducing downtime for long-shift operations.

Oil Injected Screw Compressor for Plants

Meeting the Demands of Continuous 24/7 Factory Production

In large industrial facilities like steel mills, chemical plants, and heavy machinery workshops, the compressed air system is a critical utility. If a low-tier air compressor overheats, drops line pressure, or shuts down unexpectedly during a peak shift, it can stop entire automated production lines, leading to expensive material waste, idle labor, and severe delivery delays.

The Oil Injected Screw Compressor for Plants is engineered specifically to handle these demanding, high-load factory conditions. Built with high-grade components, including an IP55-rated heavy-duty electric motor and a direct-coupled gear drive, this machine is rated for a 100% continuous duty cycle. It runs reliably day and night through demanding conditions, ensuring your factory maintains a stable, continuous supply of compressed air to keep your main assembly lines running smoothly.

Continuous Operation in a Chemical Plant

A large chemical processing facility in Zhejiang operated an older belt-driven compressor to run their pneumatic material conveying valves. Because the air system was exposed to fine chemical dust and hot ambient temperatures, the drive belts slipped frequently and wore out quickly, causing unexpected line shutdowns twice a month that cost the factory over $8,000 in lost production time.

DECHUAN fixed this issue by installing a heavy-duty Oil Injected Screw Compressor for Plants (GA26 model). Our technical team set up the direct gear-driven system with an IP55-rated high-efficiency motor. Over eighteen months of continuous 24/7 operation, the compressor has experienced zero belt-slip issues or dust-related motor failures, keeping their material conveying lines running smoothly and saving hours of emergency repair labor.

Heavy-Duty Industrial Engineering Features

1. IP55 Rated Motor Frame: The fully sealed motor enclosure prevents airborne factory dust, grit, and moisture from settling on the internal windings, preventing electrical shorts.

2. Robust Gear Transmission: Uses an efficient gearbox assembly to transfer power directly to the rotors, removing regular belt tensioning work and preventing slippage power losses.

3. High-Capacity Fluid Cooler: The large oil and air aftercooler layout keeps internal temperatures low, preventing oil thinning even during long summer shifts.

Technical Procurement FAQ

Q: What component design allows the Oil Injected Screw Compressor to manage continuous full-load cycles?

A: The compressor is built with a direct-drive gear transmission system instead of a standard belt assembly. This high-load gear configuration eliminates belt slippage and power loss, providing reliable power transfer and reduced maintenance under continuous operation.

Q: How does the system prevent airborne particulate contamination from entering the screw rotors?

A: The Oil Injected Screw Compressor for Plants features a high-efficiency air intake filter that traps fine industrial dust particles before they can enter the compression chamber, protecting internal components from premature abrasive wear.

Q: What is the recommended service interval for the air-oil separator element?

A: Under normal plant operating conditions, the heavy-duty vertical separation element should be replaced every 4000 operational hours to maintain optimal performance and keep oil carryover below standard thresholds.
