Benefits

By adding the ASPRA L1250 INduct to your ventilation system you prevent harmful fine-dust, bacteria, pollen, and fungi from entering your building and eventually into your lungs. The ASPRA L1250 INduct will increase the health of the the people indoors and it will lower the maintenance costs of your ventilation system.

The L1250 INduct is equipped with a connection diameter of 315 mm, which can be connected to any size of duct by using VFA adaptors. This INduct is used when efficient, quick and cost reduction air purification is necessary on a large scale.

The ASPRA L1250 INduct can be applied for air purification in public spaces like smoke cabins, airports, subway and train stations, shopping malls and community centers.

Product description

ASPRA® L1250 INduct

ASPRA L1250 INduct

• Equal to HEPA purification• Kills and captures viruses• Energy savings due to low pressure drop• More effective for fine particulate matter than F

or G textile/paper filters [for e.g. soot and other traffic air pollution]

• Cleaner Air Handling Unit shafts compared to using traditional filters

• No risk of fungal growth and mold like in textile/paper filters.

• Safe and easy replacement of saturated collectors by anyone

Product sizes [mm]

* LF= efficiency at low air flow ** HF= efficiency at high air flow

Every extra Pa results on average in an energy cost increase of €1,- per year. ASPRA collectors are subject to a very low pressure drop and provide an energy cost reduction compared to using conventional F9 filters.

The smaller the particle, the more harm it can cause to your health. ASPRA collectors are not only efficient for large particles, but are also very efficient for the smallest particles as opposed to conventional F9 and F7 filters.
