FLIS-EX / FLIS - Clean air in the pit / Entering pits safely

Product catalog summary

Overview: The document discusses the FLIS-EX and FLIS systems by Hermann Sewerin GmbH, designed to ensure safe entry into pits by providing clean air. These systems are crucial for preventing CO2 buildup, which can lead to unconsciousness or death, especially in confined spaces where natural ventilation is inadequate.

Specifications:

FLIS-EX: Operates at 230 V~ / 50 Hz with EX-protection (TÜV 05 ATEX 2766 EX II2G IIC T4). It has an air capacity of approximately 3.5 m³/min, motor capacity of 120 W / 0.7 A, and weighs 19 kg.
FLIS: Operates at 12 V= without EX-protection. It has an air capacity of approximately 2.5 m³/min, motor capacity of 55 W / 4.6 A, and weighs 15 kg.
Both models have a sound intensity of 60 db (A) at 1 m, dimensions of 500 x 400 x 400 mm, and a cable length of 20 m.
Operational conditions include temperatures from -15 °C to +40 °C, humidity from 0 to 90% rF, and ambient pressure from 860 to 1100 hPa.

Components and Accessories:

Includes an exhaust system with a connection cable, a flexible suction hose with a suction basket, and a flexible pressure hose.
Optional accessories include a spare quiver hose with a bayonet joint and an adapter for mains operation at 230 V~.

Recommendations: It is recommended to ensure proper ventilation in pits before entry to prevent CO2 hazards. The FLIS systems provide an efficient solution for this requirement.

FLIS-EX / FLIS - Clean air in the pit / Entering pits safely-1

FLIS-EX / FLIS Clean air in the pit / Entering pits safely The way into the depth involves great dangers. Pressure flashing in well pits as well as in ventilation pits can set free high quantities of CO2. Concentrations of more than 5 vol. % CO2 in the air lead to a dimming of consciousness, unconsciousness and even death. Possible danger also arise from nearby and probably defective gas pipelines. In close spaces natural ventilation is not sufficient. Therefore it is of great importance to provide the pit with clean and fresh air before getting into it. There is an efficient solution for this problem SEWERIN FLIS.
