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.

Ventilek advises: The WK900 is a serious "machine" that won't shy away from any job. This is where the fun stops – the 3W three-cylinder design and speeds just over nine hundred mean this unit runs completely smoothly, even when you're pushing it to its maximum. If you're fitting it to an older tank, make sure it's in good condition, because 740 litres per minute is quite a blast!
