VIQUA SHF

Model	Flow at 40 mJ/cm²	UV chamber dimensions (cm)
SHF-140	470 L/min	86.4 × 15.2 × 35.6
SHF-180	600 L/min	107.3 × 15.2 × 35.6
SHF-290	813 L/min	108 × 20.3 × 43.5

SHF flow values apply at 95% UV transmittance (UVT), 20 °C and end-of-lamp-life output.

The VIQUA SHF family brings several UV lamps together in a 316L stainless-steel chamber. SHF-140 and SHF-180 contain four lamps; SHF-290 contains five. The three models provide reference flows of 470, 600 and 813 L/min respectively at 40 mJ/cm².

Multi-lamp UV treatment for higher flows

VIQUA

A separate control panel displays remaining lamp life and provides audible and visual status alerts. The chamber and panel form a dedicated UV treatment assembly, with each model retaining its own dimensions and connection size.

The manufacturer also publishes flow values at 30 mJ/cm². These appear separately in the model tables, alongside the reference UV transmittance and operating limits, so that flow and dose remain clearly associated.
