Product Description

Maximize space efficiency by ordering a wholesale Integrated Oil-Injected Screw Compressor from DECHUAN. The Full Feature layout includes an integrated dryer with a 5°C dew point pressure rating, delivering dry, clean air that protects downstream tools from rust damage.

Integrated Oil-Injected Screw Compressor

Why Waste Time Sourcing Separate Dryers, Filters, and Tanks?

In traditional air setups, components are sourced separately, requiring extensive floor space and complex interconnected piping. This multi-joint approach often introduces flow resistance and potential air leak paths. The product solves this complexity by housing the screw element, the air receiver, the high-efficiency oil separator, and the refrigerant moisture dryer within a single sound-insulated cabinet.

This compact design minimizes your footprint and eliminates external piping assembly. Simply position the unit on the shop floor, connect your main electrical supply and air discharge manifold, and your facility has immediate access to cool, dry, high-purity compressed air.

Integrated Oil-Injected Screw Compressor

Resolving Spatial and Installation Bottlenecks in Modern Workshops

Setting up a traditional compressed air system requires linking several separate components—including the compressor, air storage tanks, cycling dryers, and fine oil filters—using an extensive network of field piping. This layout not only takes up large amounts of valuable workshop floor space but also increases the risk of air leaks at every threaded connection, causing system pressure drops and forcing you to hire expensive local pipefitters for the installation.

The compressor solves these spatial and installation problems completely. By placing all necessary air treatment equipment onto a single compact frame, this turnkey system cuts installation labor costs by up to 70%. It arrives at your facility fully wired, piped, and pre-commissioned, meaning your team simply needs to connect the main power line and the discharge pipe to start supplying clean, dry, high-quality compressed air to your production line.

Proven Structural Advantage: No Costly Installation Demands

Integrated Oil-Injected Screw Compressor

Investing in an Integrated Oil-Injected Screw Compressor from DECHUAN simplifies your facility upgrades. Standard multi-component systems require dedicated concrete pads, extensive copper plumbing, and independent electrical drop connections for each piece of hardware.

The DECHUAN system is fully pre-wired and pre-piped at our factory, reducing installation time from days to hours. It features a heavy-duty, vibration-isolated base plate that can be positioned on any flat industrial concrete floor without anchor bolts or specialized foundations.

Technical Procurement FAQ

Q: Does the integrated dryer module in the screw compressor increase overall energy costs?

A: Our smart controller coordinates the dryer's operation with the compressor's load state. During lower production periods, the dryer scales its cooling output to match the reduced air volume, preventing unnecessary power consumption.

Q: How does the built-in lossless electronic drain valve function?

A: Unlike cheap timed solenoid drains that blast valuable compressed air into the waste line every few minutes, the electronic drain in the Integrated Oil-Injected Screw Compressor uses an internal liquid level sensor. It opens only when the condensate reservoir is full, releasing accumulated water without wasting system air pressure.

Q: Is it easy to replace filters within such a compact cabinet design?

A: Yes, the enclosure features quick-release lift doors that provide full access to all consumables. The oil separator, air filter element, and inline active carbon blocks are positioned for quick, straightforward maintenance.
