HA-111 HV2 Passive Safety Earmuffs (EN 352-1)
Safety Helmets & Head / Eye / Hearing PPE

The PGTEC HA-111 HV2 is a passive safety earmuff certified to EN 352-1, designed to reduce noise exposure in industrial environments such as workshops, metal fabrication plants, pneumatic-tooling stations, quarry operators and construction sites. The earmuff uses a double-shell cup design with two layers of ABS shell separated by an acoustic spacer, which lowers resonance and improves attenuation in the mid-frequency band where impact noises from hammers and punches concentrate. The ear cushions are made from slow-recovery PU foam covered in a soft hypoallergenic PVC skin that seals comfortably around the ear without pressing on the temple, and the inner fill is replaceable for long-service use. The headband is a padded navy-blue ABS and steel-spring combination with a stainless-steel twin-bridge that keeps constant pressure on the cushions regardless of head size. The attached clips are compatible with the PGTEC SH2 and SH2R safety-helmet side slots, so the wearer can switch quickly between headband and helmet-mounted use. The nominal attenuation SNR is 27 dB, suitable for environments at 92-98 dB(A). PGTEC ships the HV2 with a spare cushion set, a multilingual instruction leaflet and a storage pouch. Each pair is batch-coded and carries a three-year warranty against manufacturing defects. The cushions can be washed in lukewarm soapy water and air-dried overnight, which keeps the seal effective across multi-year shift rotations.
