Cast iron WK900 aggregate on base frame power consumption 5.5 kW, suction capacity 900 l/min, pressure 10 bar, without air receiver, voltage 400/50 V/Hz
Code: WK900-PLATERelated products
Product detailed description
Cast iron compressor unit Walter WK900-PLATE (on a base frame) represents a high-performance industrial solution built on three-cylinder technology (3W). This model is designed for the toughest operations requiring a massive supply of compressed air while maintaining maximum mechanical resistance and long service intervals.
Industrial performance with three-cylinder stability
The WK900-PLATE model benefits from a three-cylinder block, which allows for even load distribution and efficient cooling, essential for continuous operation with a 5.5 kW motor.
1️⃣ Top-Tier GK Series Construction
✅ Cast iron 3W unit – The three-cylinder concept ensures smooth operation without excessive vibration and a top suction capacity of 900 l/min.
✅ Low speed (902 rpm) – Thanks to the Low RPM slow-running system, the unit heats up minimally, significantly reducing oil carbonization and valve wear.
2️⃣ Innovation for extreme conditions
✅ Steel filters with protective grille – A new generation of filters with a metal insert guarantees perfect intake air purity even in dusty environments of sandblasting or painting shops.
✅ Reinforced components – Modernized piston rings and valves are designed for high work intensity and guarantee maximum system tightness.
