VENTO Ergo A25-1 Pro/A25-1 S Pro
DESIGN AND OPERATING LOGIC
The unit consists of a telescopic duct with adjustable length, a ventilation
unit and an outer hood. Two filters and a ceramic heat exchanger are installed
inside of the telescopic air duct. The round Ø 107 mm air duct is made of
plastic and has an adjustable length:
- 300 up to 570 mm for the models VENTO Ergo A25-1Pro;
- 120 up to 500 mm for the models VENTO Ergo A25-1 S Pro.
The unit is equipped with a high-tech ceramic heat exchanger with heat
recovery efficiency up to 85 %. Due to the cellular structure is has larger
contact surface and high heat recovery efficiency. The ceramic heat
exchanger is featured with excellent heat-conducting properties and heat
accumulating capacity. The heat exchanger is used for extract air heat
recovery and warming up of supply air. The cord inside the heat exchanger
facilitates its removal for maintenance. The heat exchanger is installed on the
insulation material used as a sealer as well.
The ventilation unit with a flat front panel is for installation on inner side. The
automatic shutters in the ventilation unit close the air duct when the unit is
off.
Air is supplied and extracted with an axial reversible fan with EC motor and
low energy demand. The motor has overheating protection and ball bearings
for longer service life.
Two built-in filters with total filter class G3 and antibacterial coating are
used for supply and extract air filtration and the heat exchanger anti-soiling
protection. The unit is equipped with a motor meter with non-volatile
memory. After 90 days non-stop operation the sound signal reminds of the
need to clean or replace the filters. The signal is repeated every 5 minutes,
until the filters are cleaned or replaced.
The outer hood to prevents ingress of large objects and water into the unit.
The unit operation modes are controlled with a remote controller or two
three-position switches located on the unit casing.
