FNM Membrane Filter Cartridges are designed to comply with all
FDA requirements for the food industry. Nylon is particularly well
suited for water and syrup filtration. Nylon is not recommended
for filtering fermented beverages or liquids with high protein
content. Contact Critical Process Filtration to discuss using this
cartridge as a low cost alternative in compressed gas filtration.
These cartridges have been rinsed with high purity water to
ensure that manufacturing debris will not contaminate your
product. This washing also removes extractables that may affect
the taste of the product.

Changeout Pressure

82 °C (180 °F) at 10 psid
(0.69 bard) in water
35 psid (2.4 bard)

Sanitization/Sterilization
Filtered Hot Water

90 °C (194 °F), 30 minutes, multiple
cycles, max 3 psid forward flow

Autoclave

121 °C (250 °F), 30 min, multiple cycles

For all elevated temperature procedures above, a stainless steel
support ring is required.
Chemical Sanitization
Nylon does not tolerate aggressive chemical sanitization
protocols. Nylon membrane cartridges are best sanitized with
1% hydrogen peroxide or 1% hydrogen peroxide and peracetic
acid. Various manufacturers use different concentrations of
active ingredients. Refer and adhere to the manufacturer’s
instructions for sanitizing nylon membrane.
