Direct peers

• Maico Elektroapparate-Fabrik: German manufacturer of fans and ventilation systems for residential, commercial and industrial applications. Overlaps Helios almost 1:1 across axial, duct, roof and small-room fans plus smoke extraction, with a similar wholesale-led GTM in Germany.
• Systemair AB: Swedish-listed ventilation specialist selling fans, air handling units and smoke extraction across Europe, the Middle East and North America. Highly comparable product breadth (residential to commercial) and distribution model.
• Rosenberg Ventilatoren: German Mittelstand fan and axial fan manufacturer, similar in size, product range and customer base to Helios. Headquartered in southern Germany with strong industrial customers.
• Soler & Palau (S&P): Spanish/Iberian ventilation manufacturer with a broad product range including inline, axial, roof and smoke extraction fans. Similar European Mittelstand scale and channel model.

Broad incumbents

• ebm-papst: World-leading German manufacturer of electric fans and motors with a massive HVAC, refrigeration and industrial OEM footprint. Helios competes in the same air movement category but at a smaller Mittelstand scale against ebm-papst's broad global platform.
• FläktGroup: European HVAC leader offering air handling, fans and smoke management at larger scale under brands such as FläktWoods. Overlaps with Helios' commercial/industrial and smoke extraction segments but covers a much wider product portfolio.

Regional players

• Vent-Axia: UK-focused ventilation manufacturer with strong residential and commercial fan/heat recovery product lines. Closest comparable peer for Helios' UK subsidiary and its KWL/inline fan ranges.
• Broan-NuTone: North-American residential ventilation specialist (range hoods, bath fans, HRVs). A useful outside-Europe comparable for Helios' small-room fan and KWL residential product lines if Helios eventually expands west.

Emerging players

• Vents Company: Eastern-European low-cost ventilation manufacturer with growing European distribution. Head-to-head competitor in price-sensitive duct, inline and residential fan categories where Helios also competes.

Others

• Stiebel Eltron: German HVAC manufacturer (heat pumps, water heaters, ventilation). Adjacent rather than direct, but competes for the same installer and wholesale relationships in DACH and uses some overlapping residential/commercial ventilation technology.
