Miller Enterprises ML00994 LPR-100 Half Mask Respirator with Filters SM/MD

SKU CH-PTTB-5Z659 MPN ML00994

Half-mask respirator with P100 filters blocks solid dust, metal fumes, mists and vapours while a low-profile design clears welding helmets and a large exhaust valve cuts heat buildup

  • Low-profile filter design maximises field of vision for welding helmet compatibility
  • Four-point head strap adjusts for a customised, comfortable fit
  • Large non-return exhaust valve reduces heat build-up and user fatigue
  • P100 filters capture solid dust, metal fumes, mists and listed metal fumes
  • Patented filter media maintains efficiency in humidity, extending filter life

Half-Mask Respirator for Welding Use

The Miller ML00994 LPR-100 half mask protects against hazardous solid dust particles, metal fumes, mists and vapours. Its patented low-profile filter design preserves a wide field of vision and works comfortably under a welding helmet. The ergonomic mask shape and four-point head strap adjustments allow a customised, secure fit for SM/MD sizing.

Thermal Comfort and Breathing Resistance

A large non-return exhaust valve reduces heat buildup and user fatigue during extended wear. The pleated filter design increases surface area to ease breathing resistance. Patented filter media maintains efficiency regardless of humidity, extending filter life. P100 filters provide strong resistance to oil and filter airborne particulates including solid dust, metal fumes and mists.

Durable Construction and Filter Compatibility

A wrap-around spark guard shields the filter media from sparks and debris in welding environments. Filters protect against Hexavalent Chromium, Zinc Oxide, Manganese, Aluminium, Nickel, Iron Oxide, Copper, Cadmium, Lead and Beryllium fumes. Nuisance Level Relief applies to concentrations within OSHA PELs or other applicable limits. Replacement filters use part number SA00819.

Questions about this item

How do I install the filters on the ML00994 half mask, and what step do people often miss?

Align each P100 filter with the low-profile ports and twist until it locks; the step often missed is confirming both filters seat fully so the wrap-around spark guard sits flush against the mask body.

What maintenance or replacement will the LPR-100 respirator need over time?

Replace the pleated P100 filters with part number SA00819 when breathing resistance increases or the filter media shows damage; the mask itself requires only regular cleaning of the face seal and exhaust valve.

What limit appears first during sustained welding use of the ML00994?

The nuisance-level organic-vapour relief capacity is reached first; the respirator is rated only for concentrations at or below the applicable OSHA PEL, so breakthrough occurs before the P100 particulate filter loads up.
