Accessories 

You can order several accessories to tailor the system to your needs.  These accessories can be 
ordered from the factory during the week from 8:00 a.m. to 5:00 p.m. PT.   

 

 
 
Vacuum Pump

   — provides constant air flow through the 

manifold . 

 
 
 
 
 

 

 

 

Alarm Module

   — contains remote alarm contacts for up to 17 alarms (two 

required for monitoring alarms at all 32 ports). Part number 2081414-01 
 
 

 

 
 
 

Isokinetic Probes

 — for use in 

unidirectional air flow to maximize 
correlation between counts and actual 
particle-size distribution. Sometimes called 
“isoprobes.” 

 

 
 

Tubing

  

 

 

Hytrel with Teflon lining to minimize particle adhesion to walls.  
3/8" I.D. for connecting isokinetic probes to manifold, larger quantity 
typical. Part number 960380 
1/4" I.D. Hytrel for connecting manifold to particle counter, smaller 
quantity typical. Part number 960011 

Applications 

The A2432 Manifold System is designed to assist users in complying with various regulatory 
standards set by government or industry such as Fed-Std 209, ISO etc, by monitoring particulate 
levels at many locations within a facility. Pacific Scientific Instruments does not, however, have any 
responsibility or authority to inform or train its customers in the adherence to these standards. Please 
consult the appropriate regulations or regulatory agency to understand the applicable requirements 
for your facility.
