General information

Application

Slot diffusers are used as supply air or extract air diffusers in comfort zones
Suitable as mixed ventilation system for many applications due to the variety of variants and high flexibility
Unobtrusive integration into suspended ceilings
For room heights up to 4 m (lower edge of suspended ceiling)
Suitable for large volume flow rates. Wide range of applications due to optional 1- to 4-slot front rail
One-way or alternating air discharge can be adjusted on site to meet local requirements
High induction results in a rapid reduction of the temperature difference and airflow velocity (supply air variant)
For constant and variable volume flows
For supply air temperature differences of -10 to +10 K

Special characteristics

Uniform air pattern reduces contamination of the ceiling caused by the induction of room air
Horizontal, angled or vertical air discharge by means of manually adjustable air control elements
Comfortable indoor climate due to high induction and rapid reduction of temperature differences and airflow velocities
Attractive appearance due to extruded aluminium sections with anodised finish or powder coating (according to RAL CLASSIC colour scale)
The diffuser face has been optimised for maximum volume flow rate at low sound power levels
Suitable for continuous linear arrangement

Nominal sizes

LN: 600, 750, 900, 1050, 1200, 1350, 1500, 1650, 1800, 1950 mm

Variants

PL35-... :

-*: 1 to 4 slot front rail
-PF: Combination of diffuser face and plenum box with
fixed connection
-SF: Combination of diffuser face and plenum box with
detachable screw fixing
-CD: Overflow rail which can be integrated into a slotted
belt. The front rail has openings at the back through which
air can flow. The fixing of the overflow rail must be done on
site. The supplied connectors are used only for positioning
and aligning the overflow rail
-BD: Blind rail that can be integrated into a slotted band.

is no air flow through the blind rail. The blind rail must be
fixed on site. The supplied connectors are used only for
positioning and aligning the overflow rail

Slot diffusers direct the supply air from ventilation and air conditioning systems into the room, either horizontally, at an angle or vertically. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and indoor air. The result is a mixed ventilation system for comfort areas with good room air circulation and low turbulence in the occupied zone. Type PURELINE35 slot diffusers are factory fitted with manually adjustable air control elements. The airflow direction can be adjusted to meet various local requirements. Air discharge is one-way or alternating. Heating operation with vertical flow is also possible, as is angled air discharge. The supply air to room air temperature difference may range from –10 to +10 K. A damper blade (optional) enables volume flow rate balancing for commissioning. To give rooms an aesthetic, uniform look, PURELINE35 diffusers may also be used for extract air.
