Ion Source Filament for KYKY ZQJ Series Helium Leak Detectors - OEM-Compatible Replacement Consumable

One Filament Fits the Full ZQJ Range

Across the KYKY ZQJ series, the ion source cavity keeps a single mechanical standard for pin spacing, flange bore pattern and overall dimensions. Because this replacement filament is dimensionally matched to the OEM part, it drops straight into any ZQJ-series ion source with no grinding, no re-drilling and no bracket adjustment - simply remove the old filament and fit the new one.

Materials Built for a Low Detection Floor and Long Life

Yttria-Coated Iridium Filaments (2 pcs)

Vacuum-grade yttria (Y2O3) coating over an iridium base lowers the work function, so stable electron emission is achieved at a lower filament temperature. Lower operating temperature means low metal evaporation - slower ion source contamination, minimal emission drift and consistently accurate leak-rate data. Compared with common tungsten filaments, yttria-iridium delivers a markedly longer service life under the same duty.

Symmetric Dual-Filament, Precision-Wound

A symmetric two-filament layout balances electron emission for a stable ion beam, while precision winding gives a robust filament body that resists burnout under long, continuous high-temperature operation - fewer unplanned stoppages on the line.

Precision Stainless-Steel Flange

The one-piece stainless-steel flange is machined flat and corrosion-resistant for a reliable high-vacuum seal, with locating holes matched to OEM spec so the filament sits in the correct position inside the cavity for repeatable emission and collection.

Key Specifications

When to Replace & How

Replace the ion source filament when the detector fails to strike / shows no ion emission, when leak-rate readings drift or calibration against a standard leak fails, when the filament current alarms, or when a burned, deformed or broken filament is found on inspection. Typical procedure: stop and vent the source to atmosphere, disconnect wiring and remove the ion source flange, fit the new filament in the original orientation, restore wiring and seal, then pump down and re-calibrate against a standard leak. Always follow the OEM operating manual; live and vacuum work should be done by qualified service technicians.
