APPLICATION

Application

Type PURELINE35 slot diffusers are used as supply air or extract air devices in comfort zones
Suitable as mixed ventilation system for many applications due to the variety of variants and high flexibility
Discreet integration in suspended ceilings
For rooms up to approx. 4 m in height (bottom edge of finished ceiling)
For suspended ceilings, even with low gaps, due to the low height of the plenum box
One-way or alternate air distribution can be adapted to the structural conditions on site
High induction causes rapid reduction of temperature difference and airflow velocity (with supply air)
For constant and variable volume flow rates
For supply air to room air temperature differences of –10 to +10 K

Special features

Uniform air pattern reduces dirt deposits due to induced compartment air on the ceiling
Horizontal, slanted or vertical supply air distribution through manually adjustable air control blades

Functional description

Slot diffusers allow the supply air of ventilation and air conditioning systems to flow horizontally, obliquely or vertically into the room.

The flow takes place with high induction of indoor air and consequently with a rapid reduction of airflow velocity and temperature difference between supply air and indoor air.

The result is mixed flow air distribution for comfort zones with good room purging and low turbulence levels in the occupied zone.

Type PURELINE35 slot diffusers are factory fitted with manually adjustable air control elements.

Different airflow directions allow adaptation to different local conditions at any time.

Horizontal air distribution takes place with a one-way or alternating flow.

Heating operation with vertical flow is possible, as is a slanted supply air distribution.

The supply air to room air temperature difference can be -10 to +10 K.

A damper unit (optional) enables volume flow rate balancing for commissioning.

To give rooms an aesthetic, uniform look, PURELINE35 diffusers may also be used for extract air.

The quick sizing table gives a good overview of the possible volume flow rates and the corresponding sound power levels and differential pressures.

Sizing with our Easy Product Finder design programme will provide the exact values, taking all parameters into account.

The quick sizing table with one spigot applies up to 1200 mm, from 1350 mm and larger two spigots are taken into account.

Slot diffusers of Type PURELINE35 with individually, manually adjustable air control blades and 1, 2, 3 or 4 slots.

Air distribution optionally horizontal alternating, alternating angled, vertical, one-way horizontal left or one-way horizontal right possible.

The slot diffusers can be used for supply or extract air and are intended for installation in the suspended ceiling. Ready-to-install component consisting of the face plate with optional black, grey or white air control blades.

Variants with plenum boxes have 1 or 2 spigots which are arranged horizontally or vertically for symmetrical plenum boxes and horizontally for asymmetrical plenum boxes.

The plenum boxes all have 4 suspension lugs for suspension.

The connection between the face plate and plenum box is made as a fixed or detachable connection.

The spigots are suitable for circular ducts according to EN 1506 or EN 13180. Sound power level of the air-regenerated noise measured according to EN ISO 5135.

Anodised, E6-C-0, natural colour

PL plenum box, positioned on the left, in the centre, on the right

Installation and commissioning

Preferably for clear room heights up to 4.0 m
Flush ceiling installation
Duct connection horizontal or vertical
For face plates with shorter plenum boxes and non-active diffusers, there is a slot cover on the rear
For continuous linear arrangement, connect face plates to one another with alignment plates
If necessary, carry out volume flow rate balancing on the damper unit
Suitable fixing material for fixing the slot diffusers must be provided by others

The illustrations are schematic and serve to better understand the installation details.

Volume flow rate balancing

Отрегулируйте положение устройства изменения направления потока воздуха в

области патрубка так, чтобы можно было вставить отвёртку

Volume flow rate balancing

If several slot diffusers are assigned to one volume flow controller, it may be necessary to balance the volume flow rates.

Slot diffusers with plenum box and damper unit (variant -D): The flow adjustment damper can also be operated when the face plate is mounted.
