Material | Stainless steel 1.4404 (V4A) |
Construction | Frame construction made of square pipes |
Mounting | Self-adjusting spring elements with plate springs |
Mounting pressure | 240 kPa (2,35 kg/cm²) on the filter gasket |
Replacement of a spent HEPA filter is simple to perform. |
Construction | Direct-drive twin air-inlet radial ventilator |
Mounting | Fan and motor mounted in vibration-adsorbing rubber mountings |
Vibration | Motor and rotor are balanced according to performance class Q 2.5 |
The ventilator, motor and bearings are maintenance-free. |
Motor overheat cut-off with re-start lock, smooth fan start and monitoring of the condition of the pre- and HEPA filters. Alarm signal by circuit breakage to the display panel. |
The laminar air flow velocity is monitored by means of the hot-wire method which allows a permanent automatic adjustment of the radial fan. The required air flow velocity is held constant with increasing filter clogging. The air flow sensor is situated in the clean area between the HEPA filter and the protective grid. |

Filter with activated charcoal are used for adsorbing volatile substances from the air. Highly porous activated charcoal with an internal surface area of 500 - 1400 m²/g binds numerous gases and vapours principally by means of Van der Waal’s forces. The curve of adsorption as well as the adsorptive capacity of the charcoal can be obtained from the experimentally determined adsorption isotherms. Most gases with a molecular weight of 30 and more are adsorbed by activated charcoal. The activated charcoal we use adsorbs the following amount of compounds at a concentration of 1 g/m³ and a temperature of 20°C.
These data are based on the adsorption of each substance singly to the activated charcoal. |
