Casing

The casing consists of a double-skinned galvanised sheet steel with a non-flammable rock wool acoustic and moisture insulation. The motor-impeller unit can be pivoted for cleaning purposes by the generous operating door. The door hinge DIN right can be easily be converted to DIN left. Connecting pieces fit standard pipes.

Impellers

up to size 280
forward curved impeller made of galvanised sheet steel
from size 315
backward curved impellers made of aluminium
The impellers and the hubs as a unit are balanced at two levels according to G2.5 to DIN 1940.

Electrical connection

The electrical connection is on the terminal box already loosely pre-assembled on the cable. The nominal voltage is indicated on the type shield and will allow for a voltage tolerance of ±10%.

Casing

The flexible and compact EC Unoboxes ME are designed to handle air volumes with higher temperatures. A removable service door, an integrated drip pan with condensation drain nozzle, plus special sealing lips are included. The housing supporting frames are double chamber aluminum profiles with corners made of plastic and double skinned (20 mm) galvanized sheet steel panels insulated with non-inflammable, noise and temperature insulating fibreglass mats. Optionally, the outlet side (at the top or the side) can be selected. A changing of the air outlet and side panel at the installation site is possible at any time by setting of the flexible panels.

Impellers

Backward curved high-performance impellers made of aluminium are used. The impellers together with the impeller hub are dynamically balanced at two levels according to quality level G2.5 as per DIN ISO 1940.

Electrical connection

The integrated motor protection is signaled via alarm relay. The electrical connection takes place on the preassembled isolator switch in the housing. In the version „open-loop control“(standard) the speed is adjusted via 0-10V Signal or a potentiometer (accessory). The connection hereto takes place directly at the EC-Controller inside the EC Unobox ME.

Casing

The Rosenberg Unoboxes ME are designed to handle volume flows with low to medium conveying media temperatures. The housing consists of a frame made of an extruded aluminium profile with 2 chambers and plastic edges, as well as double-skinned, 20mm thick panels made of galvanised steel sheet metal with insulation made of non-combustible, sound and heat-insulated glass wool mats. The discharge and the operator side are interchangeable.

Impellers

Backward curved impellers made of high-performance aluminium are used. The impellers together with the impeller hub are dynamically balanced at two levels according to quality level G2.5 as per DIN ISO 1940.

Electrical connection

Connection will be done on the frontal mounted emergency switch.

Direction of rotation

The direction of rotation of the impellers is standard clockwise rotation (seen from the suction side). Counter-clockwise operation will cause overload damage to the motor.
