The e²short: With heat recovery

For a minimum wall thickness of 200 mm

The e² series

The e²short – equipped with the innovative polymer-based rotary heat exchanger – from the e² series is among the world’s smallest, lightest, quietest, and most sustainable decentralized heat-recovery ventilators in the single-duct category for home ventilation. This makes the unit perfectly suited for use in living rooms and bedrooms.

Special features

The e²short is the short version of the e². Only a minimum wall thickness of 200 mm is required for installation. Please refer to the table below for the exact technical specifications.

Installation

The e²short can be used in the same way as the e² in new buildings and also in renovations. The difference here is the lower wall thickness required: installation is possible from a wall thickness of 200 mm.

Extra

All products in our e² series ensure adequate air circulation in the summer without the need to constantly open windows. Learn more: You can read about how to ventilate properly in the summer here.

Approval

The e² has received building authority approval from the DIBt.

Information on the technical data

Show technical data

1) Silvento V are fan inserts that still require a flush-mounted or surface-mounted housing.

2) Silvento KL are complete single-pipe fans that are clamped into pre-wall constructions. Silvento KL single-pipe fans fit into the flush-mounted housings of the LUNOS Skalar series.

3) The specified values are achieved at 20°C, 1013hPa and 1.2kg/m3 ambient air density and (unless otherwise specified) are achievable between free-blowing condition and 60 Pa disturbance pressure in accordance with DIN18017-3.

4) When designing the volume flows, please observe the pressure-volume flow characteristics provided by LUNOS and the specifications of the abZ (DIBt approval)

5) Sound power level: The sound power level indicates how "loud" a device is. The value is independent of the distance.

6) Volume flow rate of the ALD-SV with a straight arrangement of the sound attenuation elements.

7) Max. achievable WBG according to EN13141-8 with reference volume flow rate.

8) At 70 % of the maximum volume flow rate, in accordance with ErP Directive, EU Regulation 1254/2014.

9) According to LÜA (test specification) of the DIBt and EN13141-8 max. achievable exhaust air volume flow free-blowing at 20°C and 1013hPa ambient conditions and 1.2kg/m3 ambient air density.

a) According to LÜA (test specification) of the DIBt, see also proof of usability (abZ), when using the wall-mounted housing 9/MRD as insulation, without 9/MRD 2% deduction.

b) According to LÜA (test specification) of the DIBt, max. achievable value.

c) According to EN 13141-8 with reference volume flow, see also certificate of usability (abZ) of the DIBt.

d) According to LÜA (test specification) of the DIBt and EN13141-7 max. achievable exhaust air volume flow free-blowing at 20°C and 1013hPa ambient conditions and 1.2kg/m3 ambient air density.

e) According to EN 13141-7 at reference volume flow rate, see also proof of usability (abZ) of the DIBt.

f) Determined by the Passive House Institute (PHI), see PHI certificate.

g) Sound pressure level at 1m distance, single-point measurement. All figures are mathematically rounded.
