Sentinel XL Organic Vapor/Acid Gas/HEPA Cartridges (Pack of 3)

The Sentinel XL Organic Vapor/Acid Gas/HEPA Cartridges (S-4012) combine chemical and particulate protection in one threaded cartridge for the Sentinel XL powered air-purifying respirator (PAPR). NIOSH-approved, they protect against organic vapors and acid gases, including chlorine, hydrogen chloride, sulfur dioxide, chlorine dioxide and hydrogen fluoride. They also provide HE (HEPA) filtration with 99.97% efficiency, and the filter media is strongly resistant to oil. Three cartridges thread into the Sentinel XL blower, so each pack is one full set.

Choose them when a task involves solvent vapors or acid gases as well as dust or powder, for example in pharmaceutical blending, milling, weighing and dispensing, or in chemical processing. For hazardous-drug protection, the Sentinel XL with BioShield hood is NIOSH approved with OV/AG/HE cartridges, and the Sentinel XL HD BioShield Full Hood PAPR Conversion Kit includes them. ILC Dover has also tested the S-4012 against sporicidal disinfectants based on peracetic acid, hydrogen peroxide and acetic acid, which suits teams that disinfect cleanrooms, laboratories and healthcare facilities.

For particulates only, with no gas or vapor hazard, use Sentinel HEPA P100 Cartridges (S-4002). The S-4012 is not intended for ammonia or formaldehyde, which ILC Dover's S-2027 Multi-Gas cartridge covers. It is also not a CBRN cartridge; for CBRN work, use Sentinel XL CBRN CAP 2 Cartridges (S-2016).

OSHA requires gas and vapor cartridges to be replaced on a change-out schedule. The S-4012 technical bulletin in the ILC Dover Download Center gives breakthrough times for a range of solvents and concentrations to help you set one. ILC Dover also recommends inspecting your system after each use and replacing any cartridge with mechanical damage.

Which Sentinel cartridge do I need?

All three cartridge types thread into the same 40 mm ports on the Sentinel XL blower, so the choice comes down to the hazard you are protecting against.

All Sentinel cartridges are air-purifying and do not supply oxygen, so none are for use in oxygen-deficient atmospheres. Use each cartridge only in the Sentinel configurations listed on its NIOSH approval label, and follow the user instructions.
