Dimensional & hydraulic connection schematic
Zeparo-ZUVS 20 – 7891720 – IMI Pneumatex Zeparo / Vento inžinerinis komponentas, skirtas kategorijai „Oro atskyrikliai ir nuorintuvai“. Techniniai parametrai: p
Shipped from central warehouse (delivery 2–4 bus. days)
Montuojamas šildymo sistemos magistralėje (purvo separatorius – grįžtamoje linijoje prieš katilą ar šilumos siurblį; oro separatorius – tiekiamoje linijoje). Neturi membranos ir nereikalauja priešslėgio.
Gamintojo dokumentu patvirtintas suderinamumas (vieno gamintojo sistemos ribose) · Kitiems mazgams: Suderinamumą pasitikslinkite su mūsų inžinieriumi (+370 611 19158) arba pagal įrenginio techninį pasą
Source: Manufacturer technical catalog (Danfoss / IMI Hydronic / HERZ / Haier / Gorenje 2025–2026) and LST EN 215 / EN 12828 / EN 303-5 standard
Verification note: Solid-fuel boiler door aperture and flange dimensions vary by production year and kW rating – before ordering a door conversion kit or pellet burner, verify exact dimensions against the boiler passport or with a „Gilės inžinerija“ engineer (+370 611 19158).
Material / Spec: Lakštinis plienas S235JR (3–4 mm), išbandytas 1,5×PN hidrauliniu slėgiu
Akumuliacinėms talpoms – juodas plienas; ŠV boileriams – titano emalis + 850 °C degimas.
EN 12828 sauga: tarp boilerio / akumuliacinės talpos ir apsauginio vožtuvo (3 bar šildymui / 6 bar geriamam vandeniui) bei Statico plėtimosi indo draudžiama montuoti uždaromąją armatūrą.
All [01–06] sub-assemblies, adapters, and gaskets stocked at Eigulių St. 21, Kaunas warehouse (10+ yr service support).
Confirm that 7891720 connection matches the supply/return pipework and flow direction arrow.
Depressurise the heating circuit, fit the union tailpiece and tighten to factory torque.
Adjust the flow scale (Kvs / l/h) or controller setting according to room or boiler loop load.
Refill the loop, vent trapped air and verify leak-free operation under operating temperature.
Engineer pro tip: When installing IMI Pneumatex (7891720), never wind hemp onto flat gasket seats or Eurocone O-ring cones – seal only tapered pipe threads.
Vytautas engineering compatibility note (7891720)
Verified mating components for IMI Pneumatex (7891720) matched by connection standard (DN / thread / M30×1.5 / RA Click) and hydraulic compatibility.
Yes, this IMI Pneumatex unit (SKU 7891720, category: Air & dirt separators, air vents) is manufactured to European EN 12828 hydronic standards. Verify the connection thread or nominal size (e.g. DN15 1/2", DN20 3/4", M30×1.5 or Danfoss RA Click) – our engineering advisor Vytautas lists directly compatible mating components on this page.
Genuine IMI Pneumatex components use corrosion-resistant alloys (DZR brass, bronze or stainless steel) and calibrated flow paths, preventing valve sticking, water-hammer noise and premature seal leaks over 10+ heating seasons.
When installing Zeparo-ZUVS 20 – 7891720 (7891720, retail price 206,23 €), check whether you need matching union tailpieces, Eurocone adapters, a mating thermostatic head or actuator. See the compatible parts section above.
Always observe the flow-direction arrow on the housing, depressurise the loop before fitting, and never apply hemp or tape onto flat union gaskets or O-ring cones.
