Ionising blower for cleanrooms
Key attributes of the blower include the use of cross flow fans instead of commonly used axial fans, resulting in virtually silent operation as well as increased air volumes and velocities
The new Meech 220SS cleanroom ionising blower has been developed specifically to meet the stringent environmental criteria of high specification cleanrooms and the demanding requirements for ionisation within the electronics industry The 220SS is the product of an extensive R and D programme, resulting in what Meech says is a world-leading product, for which a patent has been applied

Boosted performance from pulsed DC controller
New features include the option of steady state DC output, providing tight balance in applications where air flow is required, and connection to ion balance sensor and feedback systems
The 220SS deviates from conventional design in that it is manufactured from 316 stainless steel, with a unique tear drop profile proven to minimise disturbances to cleanroom laminar airflows.
Key attributes of the 220SS include the use of cross flow fans instead of commonly used axial fans, resulting in virtually silent operation (typically less than 50dBA at medium fan speed), as well as increased laminar air volumes and velocities.
These in turn provide excellent decay rates and offset voltages over the standard EOS ioniser test pattern.
The absence of conventional axial fans also avoids concerns regarding particulation caused by worn fan bearings - the air duct system of the 220SS ensures that no wear parts, with the exception of emitters, are in the airflow.
The unique sensor grille has been designed to be easily hinged out of the way to allow even quicker access to the removable and replaceable titanium pins.
Other standard features include ion balance and power on indicators, and switchable auto shutdown and alarm systems.
The 220SS also features an IEC socket input, eight pin DIN for data logging and RJ11 input for remote ioniser balance control, which allow balance to be controlled to typically +/-0.5V. Request a free brochure from Meech International ...
