12.6. Recirculation fan, type SST-UL V4
12.6.1. Instructions for safe use
To ensure the safe operation of the system, the following basic requirements must
be met:
• Temperature at place of installation: b10°C and +40°C
• Maximum humidity at place of installation: 60%
• Limit value for dust content in ambient air: 10mg/m³
The SST-UL recirculation fan is used to extract and clean the exhaust air from
hazardous material, safety, chemical and gas cylinder cabinets. The device
ventilates the cabinet depending on the required air change rate, filters out
hydrocarbons and indicates the current function by means of two lamps each (RED
= Error, GREEN = Service). The concentration of hazardous substances in the
exhaust air is shown in 25% steps. A concentration of 100% corresponds to the
maximum load. The DSA (dynamic saturation adjustment) function corrects the
switching point according to the ambient air quality. The device also has two
potential-free outputs for these signals. It is suitable for extracting air from cabinets
as defined in EN 14470-1 and DIN 12925 Part 2 and conforms to the requirements
of TRbF 20, TRGS 510 and GefStoffV. The user is responsible for ensuring safe
operation of the system in accordance with TRbF 20 Section 15. The statutory limit
values (TRGS 900 “Occupational exposure limit values” and TRGS 903 “Biological
limit values”) must be observed at the place of use.
PERSONAL INJURY AND MATERIAL DAMAGE
Improper use could result in broken impellers, fatigue failures or fires
due to sparks, possibly leading to personal injury or material
damage.
