CSF16 and CSF16T air sizing:

Select an air filter for a flowrate of 500 m3/h with air pressure at 4 bar g.

Step 1: Divide the flowrate required by the capacity correction factor for the operating air pressure. In this case, 500 m3/h is divided

by 0.625 for an equivalent 800 m3/h flow.

Step 2: Using the look up tables below select a filter to pass the equivalent flow in this case a 2"H CSF16 or CSF16T with a

maximum flowrate or 1080 m3/h

Please note that the flowrates displayed on the CSF16 and CSF16T air sizing table are based on an air pressure of 7 bar g.

Safety information, installation and maintenance

How to order

The following information must be specified when ordering a Spirax Sarco CSF filter:

Compressed air flowrate

Compressed air flowrate

Allowable pressure drop bar

Housing material

Size

Pipe connections

Housing seal /element seal material

m3/h

bar

(0.07 bar maximum recommended)

1.4301 or 1.4404

DN or NPS (")

EN, ASME, BSP or NPT

Note: For DN50 and DN80 high capacity version denoted by 'H' and low capacity by 'L'. For a 1.4404 housing version, the suffix 'T'

must be added to the nomenclature e.g. CSF16T.

Supply

The CSF16 and CSF16T are supplied in two parts:

1. The filter housing head and bowl with housing seal packed in one carton.

2. The filter element complete with filter element seals (2 off).

Note: The job of the filter is to remove (and retain) unwanted contamination. In time, the filter element will become saturated.

To ensure a minimum downtime, we recommend that a spare filter element set is ordered at the same time as the CSF16 and CSF16T

filter housing.

Example:

1 off Spirax Sarco DN20 CSF16 to pass compressed air at 4 bar g. Housing to be 1.4301 having NPT connections element with EPM

body seal.

1 off CSF16-A borosilicate depth filter element.
