Intake air Exhaust air Core Heat recovery q The unit is equipped with a plate counter-flow plastic core with a large surface area and high heat recovery efficiency. q Heat recovery efficiency reaches 79 %. q The air flows are fully separated within the core. Odours and contaminants contained in the extract air are not transferred to the supply air flow. q Heat recovery is based on extract air heat recovery for warming up of suply air. Extract air transfers most of its heat to the intake air flow. Heat recovery reduces heat losses in cold seasons. In summer the core performs reverse and transfers a part of the accumulated coolness from the cooled extract air for cooling down of the intake air. This contributes to better performance of the air conditioner in ventilated premises. q The integrated freezing protection system switches the supply fan off in the cold season in case of a freezing danger communicated by the temperature sensor to enable warming of the core with the warm extract air flow. When a freezing danger is over the supply fan turns on and the unit reverts to the standard operation mode. Air filtration q Supply and extract air cleaning with two MERV 4 filters. q The filters ensure fresh air supply, free of dust, insects and prevent contamination of the unit components. Control q The unit is operated with an external sensor speed switch that enables switching the unit on/off as well as setting low, medium or high speed mode. 2

Design q Polymer coated metal casing decorated with an acrylic front panel. q Heat and noise insulation is ensured by a layer of 3 / 8 cellular synthetic rubber. q The front panel provides convenient access for filter maintenance and has a lock for extra security. q The unit has two Ø 3 15 / 16 pipes for fresh air intake and stale air extraction outside. q The third Ø 3 15 / 16 pipe (included in the scope of delivery) can be additionally fitted to the unit to connect the exhaust air duct from the bathroom. q Electric preheating or post-heating is available for cold climate conditions. Air filtration q Supply air cleaning is provided by the MERV 8 and MERV 15 panel filters (PM2.5 > 75 %). q To meet more stringent air purity requirements the MERV 15 filter can be replacedwith an HEPA Filters (PM2.5 > 95 %) (purchased separately). q Exhaust air is cleaned by the panel filter MERV 8. Fans q The units feature efficient electronically commutated (ЕС) motors with an external rotor and impellers with forward curved blades. q These state-of-the-art motors are the most advanced solution in energy efficiency today. q In addition to that the efficiency of electronically commutated motors reaches very impressive levels of up to 90 %. q The unit is equipped with supply and exhaust air dampers which activate automatically to prevent drafts while the unit is off. MERV 8 Filter MERV 15 Filter Heat recovery q The FRESHBOX 100 units are equipped with a counter-flow polystyrene heat recovery core. q In the cold season the exhaust air heat is captured and transferred to the supply air stream which reduces the ventilation-generated heat losses. Some con densate may form during heat recovery. The condensate is collected in the drain pan and is removed from the exhaust air duct. q In the warm season the intake air heat is transferred to the extract air stream. This allows for a considerable reduction of the supply air temperature which, in turn, reduces the air conditioning load. q The FRESHBOX 100 ERV units are equipped with a counter-flow core with an enthalpy membrane at the core. q In the cold season the exhaust air heat and moisture are transferred to the supply air stream through the enthalpy membrane reducing the heat losses through ventilation. Consequently, it is the intake air heat and moisture transferred to the extract air stream through the enthalpy membrane in the warm season. This allows for a considerable reduction of the supply air temperature and humidity which, in turn, reduces the air conditioning load.

WALL VENTS Solo A35 Series Use q Wall ventilator with heat and energy recovery Application q Supply clean fresh air to the premises q Remove stale extract air from the premise q Clean the air of dust and insects q Prevent penetration of excessive humidity and appearance of mould q Protect against outdoor noise q Recover heat and provide humidity balance inside q Reduce the heating costs in winter and air conditioning costs in summer q Low energy demand +19.4 F +62.6 F 70 s +68 F AIR EXTRACTION +68 F Operation logic q Energy is recovered due to reversing operation of the ventilator, which consists of two cycles: CYCLE I. As warm stale extract air flows through the ceramic core, it heats up and moisturizes the core. In 70 seconds as the ceramic core gets warmed the ventilator automatically switches to Air Supply mode. CYCLE II. Fresh, cold intake air from outside flows through the ceramic core, absorbs accumulated moisture and is heated to the room temperature. In 70 seconds as the core gets cooled down, the ventilator switches to Air Extract mode and the cycle is renewed. q The Air Supply and the Air Extract modes are switched every 70 seconds. Design q Fan Air is supplied or extracted by a reversible axial fan with EC motor. Due to EC technology the fan is distinguished with low energy demand. The motor has overheating protection and ball bearings for longer service life. q Air filters Two built-in filters with total filter class MERV 7 are used to clean supply and extract air flows. The filters ensure fresh air cleaning of dust and insects and prevent the ventilator parts from soiling. The filters are cleaned either with a vacuum cleaner or flushed with water. q Energy core The high-technology energy core is used for extract air heat energy recovery and supply air heating. The Solo A35A S4 Pro P is equipped with the aluminium energy core with recovery efficiency up to 75 %.
