Qualities

AFPRO compact filters or HPQ – High Performance Quality –filters are mini-pleated filters, 

characterised by their high filtration characteristics. The glass fibre filter medium is 

made with a “wet-laid paper technique” that guarantees high dust retention effectiveness 

and constant filter efficiency. The technology guarantees sustainability,which is expressed 

as reduced air resistance and lower energy consumption. The compact filters gain an A energy 

label time and again for this very reason!

Advantages of compact filters (HPQ filters)

• Large filter area

• Spacers – hot melt

• 100% leak free

• Very great dust retention capacity

• Long lifetime

• Low energy consumption

• Dimensioning according to EN15805

• Moisture resistant

• Corrosion free

• Fully combustible

Structure

Compact or HPQ filters are mini-pleated filters that are assembled in a polystyrene frame. 

This type of air filter can withstand temperatures up to 70°C. The largely robot-automated 

production of these filters ensures that they comply with the highest quality standards.

Application

Compact or HPQ filters are used in air conditioning units and systems,

industrial systems and as pre-filters for clean rooms.

Installation

• Ensure that the filter is correctly installed:suction side – clean air side

• Filter must be correctly mounted: no leaks

• Gaskets must not be damaged

• Filter must be clamped down in four places

• Avoid touching the filter medium during installation

• Avoid damaging the filter during installation

• System must run for a few hours to achieve the desired result

• Installation record for filters: note date, time, initial resistance
