Pressure relief valve (over 100 m3, +1/10°C) ZD-1404 – how to choose the right one
The ZD-1404 is a pressure relief valve in the positive version, designed for rooms with a volume above 100 m3, drawing 36 W, with a nylon body. The construction has no telescopic adjustment.
Stating the volume as "above one hundred cubic metres" with no upper limit means that for genuinely large halls, it is worth comparing this item against those described with a specific bracket. The catalogue gives such ranges for the ZD-1403, ZD-2250 and ZD-2260.
Thirty-six watts in the positive version is a lot for a chamber where nothing freezes. This family, though, shares one construction across both regimes, and power draw in it stays independent of the temperature range.
How to match the fittings to the panel thickness and the weight of the door – we explained it in the selection guide for this category.
Where it works
- Large positive-temperature cold stores and warehouses
- Halls with a partition of a known, fixed thickness
- Installations with gradual pressure equalisation
- Fit-outs requiring a body resistant to washing

Ask a questionDoes the ZD-1404 suit a freezer?
No, the manufacturer describes this item as the positive-temperature version. For the negative range, the twin ZD-1403 is provided.
What does having no telescope mean in practice?
The construction is simpler, with fewer moving parts, but the passage length needs to be matched to the partition. It is worth confirming the dimension before cutting the hole.
