Energy-efficient variable speed base unit with filtration and external receiver: this MARK MSA 11 IVR (Inverter Variable Regulation) belt-driven rotary screw compressor automatically adjusts speed to match air demand, providing excellent energy savings (up to 30-35% vs fixed-speed), soft starts, and consistent performance.

Fully refurbished in February 2026 by Airlink Compressors engineers (airlinkcompressors.com) using only genuine MARK spares throughout. This base-mounted configuration (not receiver-mounted) includes fitted filtration (pre- and/or line filter package) for cleaner air output, and is supplied ready to connect to an external 300-litre air receiver (CE certified, vertical – customer-supplied or available separately if required) for stable pressure, reduced cycling, and buffer storage in variable-demand setups.

Key features and benefits:

• 11 kW (15 HP) premium-efficiency motor with integrated IVR (variable speed) inverter drive
• Variable speed operation – optimises energy use and reduces wear during fluctuating loads
• Working pressure: 8 bar (116 psi) – broad adjustable range typically 5-10 bar
• Free Air Delivery: up to 2.01 m³/min (71 CFM) at 8 bar (variable output higher at lower pressures)
• Belt-drive with automatic tensioning for reliable, low-maintenance transmission
• Quiet operation – approx. 65-68 dB(A)
• Advanced controller with monitoring, fault diagnostics, energy graphs, and service alerts
• Fitted filtration package for improved air quality (reduced particulates/oil carry-over)
• Integrated aftercooler for lower discharge temperatures
• Compact base-mounted canopy design with easy side-panel access – connect to external 300L tank for system stability

Full February 2026 refurbishment using genuine MARK spares includes:

• Complete air-end inspection
• New genuine air/oil separator, air filter, oil filter and full synthetic oil change
• Inverter fully tested, cleaned and re-calibrated
• Belt and tensioner system checked/replaced as required
• Thermostatic valve and minimum pressure valve service kit
• Filtration system serviced/fitted with new elements
• Full electrical safety check and controller firmware update
• 10-hour variable-load test with printed performance report
• 6-month parts & labour warranty (extendable to 12 months)

Perfect for engineering shops, garages, manufacturing, packaging or any site with variable air demand needing efficient, filtered compressed air with external receiver buffer for steady supply.
