0.004 mbar is fine on a dry bench, but in corrosive/wet duty you’ll run the gas ballast and real ultimate creeps closer to 0.05 - 0.1 mbar unless vapor handling is solid. What’s the water‑vapor tolerance with full ballast, are internals 316 or PTFE‑coated, do you support PFPE oil and a hot purge/flush mode, and what oil change interval do you recommend when pulling HCl/H2S or chlorinated solvents?
