Firstly if overly water, oil vapor, dust enter some parts absorbent like molecular sieve, these parts shall have to replaced completely. Subsequently this will affect performances of machines.
So regular maintenance is an important work to do, like replacing filter elements every 2,000 -4,000 hours.

It depends on how much gas required and its quality requirements. Different types have their advantages.

Different type has different normal pressures from 0.5 to 20bar. With compressor added any desired pressures are available.
For example PSA nitrogen generator gets 1-8bar, or 150bar with added nitrogen compressor.

O2 range: 90-99.9%.
N2 range: 95-99.9999%

Yes available. By touching screen all parameters are regulated.

Following the manual and notice to do operation is safe. Very rare there are blast for filling cylinders, unless wrong operations or poor quality of high pressure parts.

Generally available. We can design and manufacture as per your country’s law or regulation, like US standards ASME, CE standards PED etc.

Yes available. Complete monitoring of working parameters like flow, purity and alarms/reminders are within our capability. We have cloud monitoring to utilize cloud technology for the system.

Yes it is. Engineers can be sent to customers site for installation, startup, commissioning, training. Service charge USD200/day excluding travel cost.

Different types have different time. PSA unit takes normally 3-7 days to finish installation, startup, commissioning, training.
Cryogenic unit takes longer time, generally a month.
It also has to do with site preparation conditions and workers proficiency.
