The MA SD VS DS (double stage) series comprises a range of compressors at variable speed with inverter. They are designed to optimize energy consumption when running at intervals. Direct driven with an innovative separator tank device and the use of energy efficient motors, the compressors offer remarkable advantages in terms of user-friendliness, reliability, high energy savings, low noise levels and reduced maintenance costs.The series, installed in systems with discontinuous air consumption, ensures reduction of energy costs as it is able to adjust the speed of the electric motor revolutions and accordingly the speed of the airend based on the company consumption of compressed air keeping constant the running pressure of the plant. This operation mode saves energy by establishing an ideal balance between energy consumption and compressed air release. Compressors with inverter technology, controlling speed are capable of adjusting the release of compressed air to the real consumption. The electronic controller monitors and controls the electric motor and air-end speed, adjusting the airflow rate release, keeping steady the pressure in the plant.

TWO STAGE AIREND DESIGNED FOR BETTER EFFICENCY
Our new two stage airend goes through twenty finishing procedures to ensure accuracy and high reliability. The airend features optimized bearings, leading to a lifespan of 150.000 hours. The two stage design leads to enhanced efficiency and higher outputs when compared to single compression airends. The two stage airend leads to lower noise, lower vibration and increased efficiency.

ELECTRONIC CONTROL BOARD – LCD TOUCH SCREEN
Based on direct, user-friendly reading, it runs all the machine functions safely through a microprocessor, from control of safety alarms (oil temperature, electrical engine, control of cooling electrical fan, maintenance time) to command systems (startstop, alarm reset). The access to all microprocessor functions is protected by password (supplied only to authorized staff.

SYSTEM OF AIR PRE-FILTER AND VENTILATION
The series mounts a pre-filter that guarantees the utmost internal component protection, by filtering all the machine air intake. A high flow-rate electrical fan, almost noise-free, leads all the air flow into just one point, keeping up the right thermal balance for all the internal components.

AIR-OIL RADIATORS
Package model, with a wide exchange surface, designed to maintain a low level of flows and air even in an environmental condition with high temperatures. Vacuum-brazed radiators in aluminium alloy with highly efficient tubular parts. 

SOUND INSOLATION
Fitted with a professional grade double thickness soundproofing foam with fire retardant and oil resistant characteristics for maximum protection and easy cleaning.

ALL STEEL INTERNAL PIPE SYSTEM
All steel internal pipe work is used to prevent leakage and premature ageing often seen with flexible pipes. Additional to that it alowe us less pipe pressure loss.
