Halton Jaz JRP – Swirl diffuser

Swirl type ceiling diffuser unit with a square-shaped, perforated front plate.

  • High induction swirl jet ensures efficient mixing and fast reduction of air velocity.
  • The device is perfectly suited for installations with variable air flow.

Overview

Halton JRP is a swirl type ceiling diffuser unit with a square-shaped, perforated front plate.

  • High induction swirl jet ensures efficient mixing and fast reduction of air velocity.
  • Intended for suspended ceilings 600×600. The fixed swirl plate generates large inductive power which ensures effective mixing of the supply air with air present in the room, as well as enables fast temperature decrease resulting in low air velocities in the comfort zone.
  • The device is perfectly suited for installations with variable air flow.
  • Cooperates particularly well with fan-coil units operating at various speed (variable flow from 25% to 100% depending on the settings).
  • Horizontal air supply.
  • Suitable for supply and exhaust.
  • Ceiling integration installation.
  • Supply air jet velocity is effectively reduced due to high mixing effect.
  • Circular duct connection with rubber gasket.

Product models and accessories

  • Optional customisation of perforation type to customer requirements for projects is possible upon prior consultation.
  • Type for 675*675 mm ceiling available on request.
  • Sound attenuation for plenum.

Function

Horizontal radial swirl jet is supplied into the space through the profiled spiral blades
of the diffuser. Supply air jet velocity is efficiently reduced due to the high mixing effect.

Halton JRP can also be used as an exhaust unit.

Front plate

Installation

We recommended installing the plenum part into the suspended ceiling with metal hangers (not supplied in the delivery) and connected to the ductwork with the spigot equipped with an integral rubber gasket.

Adjustment

It is not possible to adjust the airflow in Halton JRP itself.

In order to enable airflow adjustment and measurement of airflow rate it is recommended to use Halton PRA adjustment and measurement unit.

Servicing

Detach the front panel of the diffuser by removing the central bolt and pulling it down, together with the swirl element.  Wipe the parts with a damp cloth.

Push the front panel and swirl element back into place and fasten the central bolt.

Specification

Halton JRP is a swirl type ceiling diffuser with a square-shaped powder-coated perforated front plate with a galvanised swirl element and plenum. The swirl element generates high induction swirl jet which ensures effective mixing of the supply air with air present in the room, as well as enables fast temperature decrease resulting in low air velocities in the comfort zone.
