Replacement Parts

27450
 
The Zero Air Generator scrubs an air sample of CO2 and H2O with a 13X molecular sieve. This sieve requires periodic replacement. Campbell Scientific offers pn 27450, which is the molecular sieve desiccant material to replace the sieve in the instrument. The sieve consists of 13 x 1.6-2.5 mm beads in a 250 g bottle. Two 250 g bottles are required to completely replace the sieve in the Zero Air Generator.
15891
 
Spare ¼ in Swagelok® plugs are available as pn 15891. This part is used to plug a fitting when the accompanying tube is disconnected, and it is necessary to keep the fittings clean. Campbell Scientific strongly recommends having spare plugs in the event that those provided with the Zero Air Generator are lost or become damaged.
4180
 
A Velcro strap is used to temporarily secure the Zero Air Generator to a crossarm or tower while carrying out the zero procedure. This strap can be replaced with pn 4180, which is a 30 cm (12 in.) length of 2.5 cm (1.0 in.) wide Velcro with a plastic loop. Campbell Scientific recommends having a spare strap in the event that the one provided with the instrument is lost or damaged.
29998
 
The original filter of the Zero Air Generator can be replaced with pn 29998. This filter is an in-line 2.5 cm (1.0 in.) diameter PTFE membrane filter of 3 micron pore size.
26064
 
The power that operates the small pump of the Zero Air Generator is supplied by a pair of AA alkaline cells. Campbell Scientific offers pn 26064, which is a long-life 1.5 V, AA alkaline battery.
