A common and crucial question we receive at EVER POWER, a premier Netherlands-based engineering firm, is: “Can I just connect a garden hose from my tap to the water lubricated compressor?” The short answer is yes to the connection, but no to the raw water entering the compression chamber. Let us explore how our advanced machinery processes tap water to protect your investment and generate 100% oil-free air.
1. Product Overview: The Guardian of Purity
Water injected compressors are the gold standard for ISO 8573-1 Class 0 air. However, raw municipal tap water is full of minerals and chlorine. To solve this, our compressors act as their own water treatment plants, guaranteeing that only the purest liquid touches the precision internal components.
- Quick Industry Applicability: Vital for pharmaceutical labs, high-end electronics, and commercial food production.
- Core Advantages Summary: Integrated filtration removes the need for expensive external water plants, preventing calcification (scale) and ensuring continuous, frictionless operation.
2. Technical Parameters (Water Interface)
To connect tap water to the compressor, you must meet basic inlet requirements. Here are the parameters for the EVER POWER EP-WI series.
| Water Parameter | Requirement | Impact on Machine |
|---|---|---|
| Inlet Pressure | 2.0 to 4.0 bar (30-60 psi) | Required to push water through the RO membrane. |
| Raw Water Hardness | < 200 ppm (Ideal) | Higher hardness reduces the lifespan of the RO filter. |
| Water Temperature | 5 – 35 degrees C | Prevents internal freezing or membrane heat damage. |
3. Working Principle: Transforming Tap Water
Yes, you connect a standard tap water line to the inlet of the compressor. But the water does not go straight to the air-end. Instead, it enters a multi-stage onboard purification process. First, an active carbon and sediment filter removes chlorine, rust from your factory pipes, and dirt. Second, a high-pressure pump forces the water through a Reverse Osmosis (RO) membrane. This membrane is so fine it strips out dissolved calcium and magnesium at a molecular level.
Only this resulting “demineralized” pure water is injected into the bronze air-end. This pure water absorbs the heat of compression, lubricates the ceramic bearings, and seals the rotors without leaving a single trace of mineral scale behind.
4. Five Core Advantages of Integrated Filtration
🚰 Simple Installation
Connect standard municipal water. There is no need to install massive external deionization plants or chemical dosing systems.
🛡️ Scale Prevention
Removing calcium guarantees that the high-precision rotors will never suffer from calcification, friction, or seizure.
🦠 Hygienic Integrity
The RO membrane naturally filters out organic bacteria from the tap water, ensuring the air produced is safe for food and pharma contact.
🧠 Active Protection
The compressor measures the electrical conductivity of the water. If the tap water overpowers the filter, the machine stops to protect itself.
♻️ Low Water Consumption
The system recirculates the pure water continuously, only drawing fresh tap water to replace the small amount lost to evaporation.
5. Structure and Corrosion Defenses
By stripping minerals from tap water, you create RO water, which is highly aggressive to standard metals. EVER POWER protects against this by eliminating cast iron from the internal water circuit. We construct our primary housings from premium bronze alloys and utilize ceramic-polymer rotors. This metallurgical superiority allows our compressors to handle aggressive, ultra-pure water continuously without suffering from rust or galvanic corrosion.
6. Typical Application Scenarios
Tap water quality varies globally, but EVER POWER normalizes it for your process:
- Remote Mining & Concrete Operations: Often rely on heavy well water. A simple external pre-softener paired with our internal RO system allows these facilities to generate clean air without destroying the machine.
- Urban Food Processing: City water is highly chlorinated to kill bacteria. The active carbon filters in our machine strip the chlorine odor, preventing it from transferring into the food packaging air.
7. Selection Guide: Pre-Installation Water Checklist
Before connecting the hose, check these three things:
- Know Your Hardness: Buy a $10 water testing kit. If your factory water exceeds 200 ppm of calcium hardness, you will save hundreds of dollars a year by installing a standard wall-mounted water softener before the compressor.
- Check Freezing Risks: The compressor is filled with water. It MUST be installed in an environment that never drops below 2 degrees C. If winter freezing is a risk, you must order the optional factory heating enclosure.
- Plan the Drain Route: The RO system will periodically purge concentrated mineral “reject” water. Because it is oil-free, you just need a standard floor drain nearby.

9. Quality Certification & Warranty
Operating from the Netherlands, EVER POWER strictly complies with CE safety standards and ISO 9001 protocols. Because our intelligent water management protects the internal components so thoroughly, we back the main air-end with an exceptional 5-year guarantee, provided the RO filters are maintained on schedule.
10. Global Case Studies
📍 Client: Paper Mill in Canada
Application: Heavy continuous industrial processing.
Feedback: “We use river water that we roughly filter. EVER POWER guided us to install a secondary booster pump and an industrial pre-filter. The compressor’s internal RO handles the rest flawlessly. The machine runs perfectly.”
📍 Client: Chemical Plant in Italy
Application: Instrument air.
Feedback: “We already had a massive Deionized (DI) water plant. We simply bypassed the compressor’s RO filter and fed our DI water straight in. EVER POWER’s open design made this customization incredibly easy.”
📍 Client: Cosmetics Factory in South Korea
Application: Mixing delicate organics.
Feedback: “The city water here smells heavily of chlorine. The active carbon pre-filters in the compressor scrub the water so well that the compressed air output has absolutely zero odor. Perfect for our product quality.”

12. Frequently Asked Questions (FAQ)
Q1: What happens if I forget to change the water filters?
A: The intelligent controller monitors the water’s electrical conductivity. When the RO filter degrades, conductivity rises. The machine will sound an alarm. If ignored, the machine will shut itself down to prevent scale from destroying the rotors.
Q2: Can I use this compressor in a freezing environment?
A: No. Water expands when it freezes. If the compressor is turned off in a sub-zero environment, the internal water will freeze and shatter the bronze housing and pipes. It must be kept above 2 degrees C, or you must drain the system entirely via the maintenance purge cycle.
