Car Park Ventilation System

In enclosed parking areas, vehicle emissions cause a significant buildup of carbon monoxide (CO) and nitrogen oxides (NOx), which pose serious health risks.
A properly designed car park ventilation system is essential to maintain air quality and ensure safety.

MYMEC GROUP provides jet fan ventilation systems in compliance with EN 12101 and NFPA 204,
ensuring effective smoke extraction and air renewal in all parking zones.

How Jet Fan Systems Work

Jet fan systems use induction airflow to distribute and exhaust contaminated air.
The jet fans accelerate air movement and push exhaust gases toward main exhaust shafts,
ensuring even air distribution and maintaining safe gas concentrations.

CO sensors continuously monitor air quality and automatically adjust fan operation when pollution levels increase.

Main Components

• Main exhaust fan

• Exhaust shafts

• Jet fans

• CO detectors

• Smoke and heat sensors

• Smoke & fresh air dampers

• Control panels and automation

In emergency situations, the system switches to smoke extraction mode to provide safe evacuation paths.

Technical Specifications

• Propeller: Cast aluminum with adjustable pitch

• Balancing: Dynamic balancing per VDI 2060 / ISO 1940-1

• Deflector: Precision-adjustable airflow direction

• Noise Control: Sound-absorbing housing for fan and motor

• Motor:

  • 2/4-pole, Dahlander dual-speed winding

  • 400V / 3Ph / 50Hz, IP55 protection class

• Isolation: Full thermal and vibration insulation

Installation and Design

System design is based on car park volume, traffic density, and required air change rate.
Jet fans are mounted openly on ceilings,
so both aesthetic appearance and technical performance are considered.

MYMEC GROUP offers circular, oval, and radial jet fan designs to match architectural preferences.
