Product Description

  • Ultra-compact 269 mm depth — fits a standard suspended ceiling void
  • 100% full and filtered automatic summer bypass
  • Wall or ceiling mountable, left or right hand
  • Rotatable spigots for flexible duct routing
  • Tool-free filter access
  • Wireless RF control as standard, ModBus/KNX BMS options
  • Passive House certified

The Zehnder EVO 4 is a balanced mechanical ventilation unit with heat recovery, designed for apartments and smaller homes where ceiling-void space is at a premium. At just 269 mm deep with a built-in condensate fall, it slides into a standard suspended ceiling without packing or shims.

EC motors hold a constant commissioned flow rate as the filters load, so Part F duty is maintained between filter changes. The summer bypass is fully filtered — pollen and particulates stay out during warm-night purge — and an A+ SEC rating keeps EPC modelling clean.

Four variants available: standard, factory-handed pre-heater (for external temperatures below -10°C), mirror-handed pre-heater, and an enthalpy exchanger version that recovers moisture as well as heat.

Suitable for

  • Apartments flats
  • 1–3 bed new builds
  • Retrofit projects with limited loft or cupboard space.

Installation

Wall or horizontal ceiling mounting. Integrated condensate fall — no shimming required. 160 mm internal duct connections, rotatable spigots. Wired by a qualified electrician via the supplied flying lead.
