Shigematsu ABEK1 Multi-Gas Cartridge Filter — Set of 2
The Shigematsu ABEK1 Multi-Gas Cartridge Filter (CA-ABEK1) is built for environments where multiple types of gases and vapours may be present at once, offering broad-spectrum protection in a single filter rather than requiring separate filters for each hazard type.
Broad Gas and Vapour Protection
This filter protects against organic and inorganic gases and vapours, sulphur dioxide and other acid gases, and ammonia and organic ammonia derivatives — a wide enough range to cover most mixed-hazard work environments. It’s specifically designed for use where multiple gases and vapours exist simultaneously, rather than a single, known contaminant, making it a practical choice for pest control, fumigation and general industrial applications where the exact hazard mix can vary job to job.
Certified Performance
The ABEK1 filter is certified and fully compliant with Australian/New Zealand Standard AS/NZS 1716:2012, and is classed as a Class 1 filter — suitable for environments with contamination levels below 1000 ppm. Confirm your job site’s contamination levels fall within this threshold before relying on this filter class alone.
Quick, Secure Fitting
A twist-lock connection secures the filter to the STS mask quickly and easily, without fiddling with additional hardware — useful when filters need to be swapped out in the field between jobs or hazard types.
Mask Compatibility
This filter is compatible with the following Shigematsu masks:
- RS01 — Thermoplastic half mask
- RS01SD — Premium silicone half mask
- CF01 — Full face mask
- FS01 — Full face mask
Pack Size
Two filters are required per mask (one per side), and this listing is sold as the matching set of two — exactly what’s needed for a single respirator.
Choosing the Right Filter
Filter selection should always be based on the specific hazards present at your job site. Use the filter selection calculator to confirm the ABEK1 is the correct filter class for your application, particularly where contamination levels or hazard types are uncertain.
Adding Particulate Protection
For jobs involving both gases and particulates, pair this filter with the Shigematsu P3RC Clip-On Pre-Filter, which clips directly onto this cartridge to create combined gas and particulate protection.
Where It’s Used
- Pest control and fumigation work involving mixed gas hazards
- Industrial environments with organic/inorganic gas or vapour exposure
- Sites with sulphur dioxide, acid gas or ammonia exposure risk
- Any application requiring Class 1 (sub-1000ppm) gas protection
