Filter-fan-units in cleanrooms

More than just moving air

The demands on filter-fan-units in cleanroom technology are significant

Special rooms come with special demands. In cleanroom operation, this means clean air with a high air exchange rate, sufficient pressure, exact temperature and humidity control, and air quality that is always consistent. To achieve all this, powerful ventilation systems (filter-fan-units) are required.

Filter-fan-units are used to supply production and filling facilities with ultra-clean air. They are mainly employed in ceiling-mounted systems in clean rooms in chip factories, bottle filling or plastic mold-ing facilities, the pharmaceutical industry and microstructure technology. These applications need everything to work together perfectly with reliable and durable fans.

These units made up of filter technology and fan ensure the required recirculating air mode. They also prevent contamination in the air and damage or impairments when producing sensitive products. In addition, bob手机APP官方下载链接 FFUs are extremely quiet, satisfying the strict noise protection conditions for production in clean rooms.

The advantages of FFU products from bob手机APP官方下载链接 in clean rooms:

A controlled cleanroom atmosphere is produced by a ventilation system that regulates the supply of clean fresh air, in order to keep the particle content of the air to a minimum.

Whether analogue or digital, our various interfaces make every connection simple, secure, and fast.

MODBUS / 0-10 V combination input for digital or analogue control with MODBUS RTU or potentiom-eter

For fan units with MODBUS/0–10 V, the set value source can be changed from 0–10 V (factory set-ting) to MODBUS RTU. This series can be controlled both with an (analogue) 0–10 V signal and with MODBUS (digital).

Speed control possible with potentiometer or any 0–10V source, e.g. laminar flow con-troller
Remote querying of any 0–10V sensor (e. g. pressure) connected to the analog 0–10V input of the fan
Speed setting using any MODBUS RTU master

MODBUS / DCI autoaddressing function for cleanroom

Fans with MODBUS/DCI interface can be addressed via a voltage signal of 15 V/24 V DC (Init pin at pin 8 of the RJ45 plug).

Only the unit activated with the Init pin listens to messages sent to slave address 247 and accepts a new MODBUS address written by the master control to this 247 address. After a unit is successfully addressed its DC relay is switched on and the 15 V/24 V Init pin is forwarded to the next fan module in the chain.

This fan is now activated via the hardware signal (Init pin) and address-ing continues as described above.
