Hi RL,

While it's only been a short while our operator has been using it for two
days straight and likes it a lot. No signs yet of saturation of the
cartridges and he is having no trouble breathing. Like I said yesterday the
vent is overhead and draws the fresh air in from behind the operator. About
all that's going into the tubes is fresh air from the shop.

I'll let you know if this attitude changes.

Best regards,

KennyB

Breathing through a schnorkel is not made easier by doubling the number of
tubes. This looks like a misapplication of hardware by the vendor. Suggest
you try it yourself first, before applying it.

I find it hard to believe that IPA vapour concentration is significantly
reduced behind the operator's back.
