Transitioning a factory from traditional oil-flooded air compressors to a 100% oil-free system is a massive step forward in product quality and environmental compliance. However, simply swapping the machine isn’t enough; the entire pneumatic ecosystem must be prepared. As an elite engineering manufacturer based in the Netherlands, EVER POWER provides this comprehensive guide to smoothly transitioning your facility to water-injected technology.
1. Product Overview: The End Goal
The goal of transitioning to an EVER POWER water-lubricated compressor is to achieve ISO 8573-1 Class 0 air purity. This ensures zero risk of oil contamination in your products, eliminates hazardous oil waste disposal, and utilizes isothermal compression to significantly reduce your monthly electricity bills.
- Quick Industry Applicability: Facilities upgrading for ISO 22000 (Food), FDA compliance, or modernizing for corporate sustainability goals.
- Core Advantages Summary: A properly executed transition permanently removes hydrocarbons from your pipeline, maximizing the lifespan of your robotic tools and safeguarding consumer health.

2. Phase 1: Pre-Installation Audit (The Checklist)
Before purchasing the new EP-WI series compressor, our engineers recommend evaluating your current infrastructure.
| Infrastructure Area | Current State (Oil-Flooded) | Required Action for Oil-Free |
|---|---|---|
| Main Air Piping | Galvanized or Black Iron (Oil-soaked) | Replace or Professionally Clean. Install Aluminum or Stainless Steel. |
| Air Receiver Tank | Coated in heavy oil sludge | Replace. Buy a new epoxy-coated or stainless steel receiver. |
| Water Supply | None connected | Route tap water line to the compressor location (2-4 bar pressure). |
3. Working Principle: The Pipe Contamination Problem
If you connect a brand new EVER POWER Class 0 compressor to a piping network that has been fed by an oil-flooded compressor for ten years, your air will still be contaminated. The inner walls of your factory pipes are coated in residual oil varnish. As the new, clean, oil-free air moves through the pipes, it acts as a solvent, stripping that old oil off the walls and carrying it directly into your products. To truly achieve Class 0 purity, you must either conduct a chemical flush of the old pipes or, ideally, install a modern aluminum piping network alongside the new compressor.

4. Five Core Steps for a Flawless Transition
📏 Step 1: Right-Size the Machine
Do not blindly match the kilowatt rating of your old compressor. Because you will be removing massive inline carbon oil filters, you will eliminate pressure drops. You can often buy a smaller, more efficient VFD compressor to do the same job.
💧 Step 2: Address Water Hardness
EVER POWER units have internal RO systems. However, if your tap water is extremely hard (>200 ppm), installing a cheap wall-mounted water softener before the compressor will protect the internal RO membranes and save maintenance costs.
❄️ Step 3: Upgrade the Air Dryer
Water-injected compressors produce 100% humid air. Ensure your refrigerated or desiccant dryer is adequately sized to handle the CFM flow and remove the water vapor before it hits the factory floor.
🧪 Step 4: Purge or Replace Piping
If you cannot replace your main headers, hire a specialist to chemically purge and steam-clean your existing pipework to remove decades of legacy oil sludge.
🎛️ Step 5: Reprogram Line Pressures
Since the air is now flowing without the restriction of heavy oil filters, you can likely reduce the central generation pressure on your VFD controller by 0.5 to 1.0 bar, instantly saving up to 7% on electricity.
5. Structure and Space Planning
EVER POWER water-injected systems are designed to be compact, housing the air-end, VFD, and RO water purification all within one soundproof canopy. When planning your new utility room layout, ensure there is at least 1.5 meters of clearance around the machine for optimal cooling ventilation and easy access for maintenance technicians to change the water filters.

6. Decommissioning the Old System
Once your new EVER POWER system is online, decommissioning your old oil-flooded unit properly is vital. You must safely drain all synthetic oil and legally dispose of the toxic oil-water separators. Enjoy the fact that this will be the last time you ever have to pay hazardous waste disposal fees for your compressed air system!
