Within the O&M.
Inside the part on General Warning.
Is a statement that this product is intended to be used with a filtered vacuum system.
See attachment below.
The factory has been slow to get back to me / so my question is:
1) is it the filter in the suction canister at the regulator in the patient room ?
or
2) is it the HEPA Filters listed in the 2018 Edition of NFPA 99 ?
