Shigematsu RS01SD Premium Silicone Half Mask — Large
The Shigematsu RS01SD is a premium silicone half mask built for wearers who need genuine comfort during extended respirator use, without sacrificing certified protection. This large-size listing suits wearers who find the medium fit too tight across the face, and features the same speech diaphragm, silicone facepiece and drop-down harness as the rest of the RS01SD range.
Premium Silicone Comfort
Unlike thermoplastic half masks, the RS01SD’s facepiece is made entirely from silicone, offering enhanced softness, comfort and durability. For anyone spending long stretches in a respirator — pest control technicians, spray applicators, industrial workers — that difference in comfort can make a real impact over a full shift.
Built-In Speech Diaphragm
A speech diaphragm is integrated into the mask, allowing clearer verbal communication while the respirator remains fully sealed. This is a genuine practical advantage on job sites where coordinating with colleagues or clients while masked is a regular part of the work.
Drop-Down Harness for Helmet Compatibility
The RS01SD features a drop-down head harness, meaning the mask can be lowered or raised without needing to remove a safety helmet first. For workers who move in and out of respiratory protection frequently throughout a job — stepping away from a spray area, having a conversation, checking equipment — this saves real time and hassle compared to masks requiring a full harness removal.
Quick Filter Changes
A twist connector secures filters to the mask, making change-outs fast and straightforward in the field. The RS01SD uses “CA series” filters with bayonet connectors — refer to the compatible filters guide to confirm the right filter for your application before ordering, since filters are sold separately from the mask.
Certified Protection
The RS01SD is certified to EN 140:1998 and AS/NZS 1716:2012, as well as EU Regulation 2016/425 — giving it recognised certification across both the New Zealand/Australian and European regulatory frameworks. Full technical specifications are available in the product info sheet.
Choosing the Right Size
The RS01SD is available in Small, Medium and Large. If you’re unsure which size suits your face shape, the Medium version is also available — a proper fit test is recommended for any respirator to ensure an effective seal.
Compatible Filters
Pair this mask with the Shigematsu ABEK1 Multi-Gas Cartridge Filter for gas and vapour protection, or add the P3RC Clip-On Pre-Filter for combined particulate and gas filtration. Use the filter selection calculator to confirm the correct filter class for your job.
