Train limiter Z4 130 x 190 mm

The Upmann Z4 draft regulator is approved for use with oil, gas, and all solid fuels, whether in new installations, renovations, or all conventional systems. These systems require a specific and constant negative pressure for operation. If the chimney draft exceeds the value for optimal draft, the damper of the chimney draft regulator opens, reducing the negative pressure by allowing additional air to flow in. Once the preset value is reached, the damper of the Z4 draft regulator can be closed again. The Z4 draft regulator is made of stainless steel and designed for installation in the chimney wall.
