This filter with fan provides positive extraction and monitoring of chemical storage cabinets, in the form of almost 100% decontamination of the extracted air by molecular adsorption filtering of harmful solvent vapors (hydrocarbons). The filter operation means optimum protection for the user. As a consequence, no additional air extraction outlet is needed, which, in turn, allows the filter unit to be operated immediately next to, or on top of, the storage cabinet. The decontaminated air is released into the ambient air, thereby not consuming any heated or air-conditioned air from the room. A sensor monitors the extraction airflow and triggers a visual and audible alarm when no airflow above the set threshold is detected. The enclosure is made of silver pearl glimmer, powder-coated sheet steel. As an air extraction system, it as of today complies with “green lab” requirements, while offering you full flexibility of position. The multi-stage, grounded filtering system offers dual safety, being composed of:
Activated carbon filter with twice as much activated carbon — for up to 100% decontamination
Additionally a DIN EN 779-compliant particulate filter
The filter alert appliance can be set at the differential pressure meter/switch. The filter elements themselves and the filter enclosure lid are monitored by ATEX-compliant micro-switches. The three-month check and replace interval of the activated carbon filter is verified by a check report the user has to confirm which is paired to a scheduler. The product ships ready for plug-in.

This extractor provides easy airflow monitoring of chemical storage cabinets. The airflow monitoring unit with integrated fan ships preassembled to be installed immediately on top of the storage cabinet. The enclosure is made of silver pearl glimmer, powder-coated sheet steel
A sensor monitors the extraction airflow and triggers a visual and audible alarm when no airflow above the defined minimum is detected. The air monitoring unit fan ships preassembled to be installed immediately on top of the storage cabinet. The alarm threshold for the airflow velocity is factory-set, but can be customized at the differential pressure meter/switch. The airflow sensor monitors the actual extraction velocity and the entire extraction system of the storage cabinet. Both the volumetric flow and the power supply are sensed by a microcontroller unit. When airflow velocity drops below the set threshold, visual and audible alarms are set off. The system ships with two potential-free (“dry”) contacts (24 V, 2 A) that can be used to send an alarm signal to the control center. An integrated battery cuts in in case of power supply failure, and the monitoring system and the display, including simple error messaging, can run on it for 4 hours. The product ships ready for plug-in.
With the HÜRNER quick mounting system, the clamps can be replaced easy as ABC. The chassis/carriage, without the RH and LH pipe‑aligning clamps, can be removed from its steel frame by simply loosening 4 mounting screws and can then be used in areas that are hard to reach or overhead.
Both the operation of the clamps for the straight pipe and the saddle fitting and the movement of the carriage for the latter are implemented as using ergonomically designed handwheels. Additionally, the motion handwheel can be removed easily, to move the clamping chassis/carriage with a common power tool (cordless drill/screwdriver) as its drive.
A special mention deserve the heating element seat next to the chassis for clamping the saddle fitting, on which to place the heating element, and the two freely adjustable depth setpoints. The easy insertion and safe and swift removal of the heating element, including centering and an auto‑detaching step in the change‑over stage, bring a use as convenient as to be considered unique.
The insertion depth setpoints provide, on the one hand, consistent fusion depth and welding position and, on the other, shorter length of movements, thus faster change-over.
Special octagonal clamps for branch‑off fittings, of various wrench sizes, are also available.
