Product Description

DECHUAN as a professional Workshop screw compressor Manufacturer provides compact, ultra-quiet, all-in-one air solutions purpose-built for small to medium manufacturing workshops, custom furniture factories, precision machining rooms, and auto body painting bays.

Compact Footprint – Designed to Fit Small and Medium Workspace Layouts

Sub-1m² Floor Space Saves Valuable Production Area

In a typical 200m² job shop, every square meter counts. DECHUAN occupies less than 1 m² of floor space – roughly the area of one standard pallet. The vertical or horizontal configuration allows you to push the unit against a wall, into a corner, or even under a workbench (for sub-7.5 kW models). While competitors' "skid-mounted" units sprawl across 2–3 m² and block forklift aisles, our compact design keeps your layout efficient.

Dimensions at a Glance

Model (kW)	Width (mm)	Depth (mm)	Height (mm)	Floor Area (m²)
5.5–7.5 kW	650	800	900	0.52
11–15 kW	750	900	1,050	0.68
18.5–22 kW	850	1,000	1,200	0.85
30–37 kW	950	1,100	1,350	1.05

Ultra-Low Noise Levels (<62 dB)

Why Noise Matters in Shared Workspaces

OSHA and EU occupational standards set an 8-hour exposure limit at 85 dB. But in a typical 30m×15m workshop where eight machinists work within 10 meters of the air compressor, every 3 dB reduction cuts noise energy in half. DECHUAN Workshop screw compressor operates at ≤62 dB at 1 meter distance – quieter than a conversational voice (65 dB) and far below the 75–85 dB of conventional piston compressors or open-frame screw units.

Four Layers of Noise Control

Low-speed cooling fan: Large-diameter, aerodynamically optimized fan runs at 1,450 rpm instead of 2,800 rpm, eliminating high-frequency whine.
Acoustic canopy: 50mm-thick polyurethane foam (fire-retardant UL94 V-0) lining all panels, with staggered seams to prevent sound leaks.
Isolated airend mounting: The screw airend sits on rubber-metal sandwich mounts; no rigid contact with chassis.
Silenced intake filter: Helical intake tract with internal baffles reduces induction roar.

Real-World Noise Comparison

Equipment Type	Typical dB(A) @ 1m	Can Workers Talk Normally Nearby?
Reciprocating piston compressor	78–85	No – shouting required
Budget screw compressor (no canopy)	72–78	Difficult – raised voice needed
DECHUAN Workshop screw compressor	58–62	Yes – normal conversation possible
Office copier/printer	50–55	Completely comfortable

Air Quality Guarantee

The integrated dryer and filters deliver compressed air meeting ISO 8573-1 Class 2.4.2:

Solid particles: Class 2 (≤1 μm, ≤1 mg/m³)
Water content: Class 4 (pressure dew point +3°C)
Oil content: Class 2 (≤0.1 mg/m³)

This quality level supports paint spraying, CNC tool changers, pneumatic measuring instruments, and food-contact packaging.

The Workshop Air Usage Pattern – Very Different from Factories

A large factory runs air tools continuously for 16 hours/day. A small workshop, by contrast, sees:

High demand for 10 minutes (blowing chips off CNC machines, running a sander)
Zero demand for 5 minutes (worker moves part to next station)
Moderate demand for 15 minutes (pneumatic clamping)
Repeat cycle unpredictably

Conventional fixed-speed compressors respond by: load → unload → load → unload. Each unload period still consumes 25–40% of full-load power while producing no useful air. Over an 8-hour shift, this wastes 35–50 kWh – money that buys nothing.

Two Smart Solutions for Intermittent Use

Option A – Auto Start/Stop (Fixed Speed + Timer)

Our basic control panel includes a pressure switch with configurable start and stop bands. When no air is demanded for a set delay (adjustable 1–30 minutes), the Workshop screw compressor shuts down completely – zero power draw. When pressure drops to the restart threshold, it restarts automatically. This suits workshops with predictable idle gaps longer than 5 minutes.

Option B – Permanent Magnet Variable Frequency Drive (PM VFD)

For highly variable demand (e.g., a custom furniture shop where sanders, nail guns, and spray guns start and stop constantly), PM VFD technology matches motor speed precisely to air demand – from 20% to 100% of rated flow. Savings over fixed-speed: typically 25–40% on electricity bills.

After-Sales Support for Small Workshops

We understand a small furniture maker in Vietnam or an auto refinishing shop in Peru does not have an in-house maintenance engineer. Therefore:

Every Screw compressor ships with a laminated quick-start card (pictures only, no language barrier)
Video library (YouTube, Bilibili, Facebook) shows oil change, filter swap, drain valve cleaning – each video under 2 minutes
Spare parts kit (belt, filters, O-rings) can be ordered alongside the compressor; we pack it inside the same crate – no separate freight cost
WhatsApp technical support – message us a photo or video, receive a reply within 8 business hours (same day for Asia-Pacific)

Ordering Process and Delivery

Select kW and voltage – Use the table above or email us your tools list (sanders, spray guns, nailers, CNC air consumption) for free sizing recommendation.

Request a proforma invoice – We quote EXW Shanghai or CIF your nearest port.

Production lead time: 15–25 working days (stock units available for 11kW and 15kW, ship within 5 days)

Shipping: Export wooden crate (humidity-proof, fumigated ISPM15). We arrange sea freight or air freight as you instruct.

Every DECHUAN Workshop Screw Compressor includes a 24-month manufacturer’s warranty (12 months on dryer and filters). For customers ordering 5+ units, we offer a consignment spare parts package and a free onsite startup training via video call.
