Filling Isolator Maintenance

A filling isolator is a glove, a differential, a transfer port, and a HEPA. The pressure cascade and the fill parameters stay where the site left them.

Components To Track

ChatterFix builds these as child assets under filling isolator, so failure history and PM completions attach to the component that actually failed — not just to the machine.

How Filling Isolator Actually Fails

The failure modes worth designing a maintenance schedule around — in rough order of what they cost when they happen.

  • A glove with a hole left in the port
  • Differential read on the wrong gauge
  • Transfer-port seals that no longer seat
  • HEPA differential ignored because the room cascade was adjusted instead
  • A failed glove left in service for the rest of the lot

What To Measure

Recording that a PM was "done" tells you nothing next quarter. These are the readings that let you see a failure coming — and the reason ChatterFix captures measurements against the asset rather than just completions.

  • Glove ports for holes, cracks, and the correct glove
  • Isolator differential on the site's gauge
  • Transfer-port seals
  • HEPA differential
  • That the cascade and the fill were not changed

Spares Worth Stocking

Common Questions

What maintenance does filling isolator need?
ChatterFix schedules 13 routines against this asset: additive machine filter & atmosphere check (every 2 weeks), aeration blower filter and bearing (monthly), air filter replacement route (quarterly), co2 sensor panel calibration record (monthly), crac unit filter and coil (monthly), cleanroom air handler filter differential (monthly), drying room air handler filter (every 2 weeks), dust collector filter & explosion vent inspection (quarterly), engine oil & filter service (semi-annual), filling isolator glove and pressure check (weekly), hydraulic oil sample & filter change (quarterly), paint booth filter & airflow balance (monthly), tyre rotation & pressure check (quarterly). The readings that matter most are glove ports for holes, cracks, and the correct glove.
How does filling isolator usually fail?
The most common modes are: a glove with a hole left in the port; differential read on the wrong gauge; transfer-port seals that no longer seat; hepa differential ignored because the room cascade was adjusted instead; a failed glove left in service for the rest of the lot. Most of these degrade gradually rather than failing outright, which is what makes interval-based inspection worthwhile.
What spare parts should we stock?
Isolator gloves, Transfer-port seals, HEPA filter, Glove-port rings, Differential gauge the site specifies. The test is lead time, not cost: stock the part whose absence turns a two-hour repair into a two-week outage, even if it is cheap.
Can I track this in ChatterFix?
Yes. Pick your industry at signup and filling isolator is created as an asset with its 4 tracked components, with its PM schedule already attached. Technicians then log readings and findings against it by voice rather than typing them in.
