General information

Application

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

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

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

Intermediate sizes of the diffuser face are also available (in increments of 1 mm)

Variants

PL50-... :

-*: 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

-PB: Plenum box only (for combination with DS)

-DS: only front rail with B00 profile and screw fixing

-DF: only front rail with B00 profile and spring clip

-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. The diffuser face is closed on the reverse side so that there 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

-CS: Corner section

Position of the plenum box on the diffuser face, if the plenum box is shorter than the diffuser face

Central position of plenum box

Plenum box on the left (LE)

Plenum box on the right (RI)

Plenum box variant

Symmetric position of plenum box, side entry spigot (HS)

Symmetric position of plenum box, top entry spigot (VS)

Asymmetric position of plenum box, side entry spigot (HA)

EA: 2 end angles

Single diffusers are factory fitted with end plates or end angles. Either end plates or end angles can be used for the front end for continuous linear arrangements.

Accessories

EP: 2 end plates

EA: 2 end angles

For slot diffusers as continuous linear arrangement, the end plates or end angles must be ordered separately and installed on site. 2 alignment plates for connecting the front rails to each other are supplied separately with each slot diffuser without a factory-fitted end piece.

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 PURELINE50 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, Type PURELINE50 diffusers may also be used for extract air.

Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures.

Exact values for all parameters can be determined with our Easy Product Finder design program.

Up to nominal length 1500 mm, sizing includes one spigot; from length 1650 mm, two spigots are required.

Specification text

Slot diffusers of Type PURELINE50 with individually manually adjustable air control elements and 1, 2, 3 or 4 slots.

Air distribution can be alternating horizontal, alternating angled, vertical, one-way horizontal to the left or one-way horizontal to the right.

The slot diffusers are intended to be installed in suspended ceilings and are suitable for supply air and extract air. Ready-to-install component which consists of a diffuser face with black, grey or white air control elements.

Variants with plenum box have 1 or 2 spigots. Symmetrically positioned plenum boxes may have side entry or top entry spigots. Asymmetrically positioned plenum boxes have only side entry spigots.

The plenum boxes are fitted with 4 suspension lugs.

The diffuser face fixing can be detachable or non-detachable.

Spigots are suitable for circular ducts according to EN 1506 or EN 13180. The sound power level of air-regenerated noise is measured according to EN ISO 5135.

Special features

Uniform air pattern reduces contamination of the ceiling due to induced 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 (RAL CLASSIC colour)

The diffuser face has been optimised for maximum volume flow rate at low sound power levels

Suitable for continuous linear arrangement
