The MA SD series, direct driven, guarantees important and cuttingedge advantages and is embodied by a compact, easy-to-use system, occupying just a modest amount of space, with a noticeable power efficiency and a significant long lifecycle. Total function control through a user-friendly electronic board. Extremely low noise levels as well as reduced maintenance costs and times. Direct driven system and hi-efficiency motor ensuring the highest reliability in any work condition. Reduced overall dimensions and simplified installation are a winning card to overcome space problems.

DRIVING SYSTEM
Direct-driven compressors with a 1:1 ratio. This means that the airend and motor, directly connected via a coupling, rotate at the same speed. This not only reduces energy consumption and maintenance need, but it also decreases the level of noise. The use of highefficiency motors provide saving if compared to the performance of traditional compressors.

ELECTRONIC CONTROL BOARD
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 INSULATION
Fitted with a professional grade double thickness soundproofing foam with fire retardant and oil resistant characteristics for maximum protection and easy cleaning.
