Fan
The R4000 uses an electronic motorised impeller (EC motor) satisfying the fan electricity
consumption reduction standards (Erp 2015 directive). It allows a very precise, quiet regulation from 0-10V,
maintaining a constant flow and adapted timing according to the issues to be treated and the environment.
For example, the available pressure is 950 Pa at 3,000 m

Connection to a ventilation network
The R4000 is a mobile, autonomous air handling unit. In some cases (e.g. location in a class 4
hazardous zone, centralised treatment of several rooms, etc.), it can be connected to a ventilation system
using an optional painted galvanised steel connection mounted on the unit by tightening on a seal. It can
thus be connected to ducts of diameters ranging from 150 (DN150) to 400 mm (DN400). Other connection
components are available (consult us):
•
Fixed connection kit,
•
Fixed suspended filter ceiling with unidirectional flow equipped with terminal filters for zone 4,
•
Removable filter ceiling with unidirectional flow equipped with terminal filters for zone 4,
•
Flow diffuser box for zone 3,
•
Negative pressure kit,
•
Mobile kit for overpressurisation with isolation panel for the fresh air intake,
•
Air-mixing plenum (return air / fresh air) incorporating air heating and cooling batteries.
