Uncompromisingly compact. Maximum performance in minimum space

The combiloop CL4G-300 combines energy-efficient high-pressure coolant supply up to 300 bar, high-pressure and bypass filtration, separate spindle flushing and optional temperature management in a highly compact integrated solution. Available with either a compact belt filter or self-cleaning automatic filter, with filtration capacity up to 60 l/min at 40 μm and a 300-litre clean tank. For cutting oil and emulsion.

High pressure redefined: With a footprint of just 0.96 m², the CL4G-300 combines essential coolant processes for Swiss-type lathes, lathes and compact machining centres. Achieve maximum precision and increase your profitability without sacrificing valuable floor space.

Technical data combiloop CL4G-300

Characteristic	Version
Equipment	1,200 x 800 x 1,850/2,200 mm (L x W x H), weight approx. 650/750 kg 40–300 bar, eco+ pressure-regulated piston pump or screw spindle pump, 300-litre clean tank, electrical control system, flow monitor and pressure control
Flow range	0–60 l/min, depending on performance configuration (60 l/min max. filtration capacity of the system at 40 μm)
Pressure (examples)	Option 1: 20 l/min at 150 bar and 20 l/min at 15 bar Option 2: 37 l/min at 70 bar and 20 l/min at 15 bar Option 3: 45 l/min at 70 bar and 12 l/min at 15 bar Many other configurations available (on request)
Filter / Filter fineness	Automatic filter (40 μm), bypass filtration, desludging in a dedicated tank section with automated scraper discharge Compact belt filter (40 μm) with collection basket for used filter fleece, bypass filtration
Operation	Cutting oil Water emulsion (min. 5% oil content)
Service connections	Up to 10 switchable outlets
Options	Active cooler, 7.5 kW (modular installation on top of the base unit) Plate heat exchanger up to 10.0 kW Frequency inverter Orange LED alarm when 80% of the filter fleece has been used Separate second pump for spindle or cover flushing from the clean tank
Degree of machine contamination more	Our recommendation for: Low degree of contamination (e.g. free-cutting steel, coarse chips, few fine chips) Medium degree of contamination (e.g. free-cutting steel, stainless steel, mixed fine/coarse chip ratio) High degree of contamination (e.g. aluminium, brass, cast iron, titanium, mainly fine chips from finishing and milling operations) Ultra-fine contamination throughout the machining process (graphite machining, ultra-fine finishing, high sludge volume, high proportion of grinding processes)
