Whether H1 is required depends on the contact path between the pump and the product, which is a HACCP determination.
NSF H1 designates a lubricant formulated for use where incidental contact with food is possible. Whether it is required on a given vacuum pump depends on whether a contact path exists between the pump and the product.
Where no contact path exists, mineral oil is the correct specification. Where one exists, food-grade lubrication is a HACCP matter.
H1 lubricants are formulated for incidental contact. The registration is a control for contact that was not intended but may occur: a leaking seal, oil mist carried in an exhaust, or a drip onto a surface that later meets product.
The manufacturer's own vacuum pump oil guidance describes its standard mineral grades as suitable in many industries, and names food among the industries requiring synthetic oils.

The viscosity grade is the same, so the product is a drop-in on grade. Whether the existing charge requires flushing before the food-grade oil is introduced has been put to the manufacturer. No published answer has been located, so none is stated here.
The assessment belongs to the plant's HACCP team. On a vacuum pump there are four places to examine.
Where none of these paths exists, mineral oil is correct and no change is recommended. Where one exists, it is the type of finding an audit will identify.
Fuchs Cassida holds NSF H1 and ISO 21469. H1 certifies the formulation; ISO 21469 audits the manufacturing and handling behind it. Fuchs describes the combination as the strictest food-grade lubricant certification available. The range is Halal and Kosher certified.

MOSH and MOAH, the transfer of mineral oil hydrocarbons into foodstuffs, is a tightening European regulatory concern. It is relevant to any plant exporting to Europe or supplying a customer who does.

Whether a contact path exists in a given plant has not been established here. It is a HACCP determination and it is held by the plant.
Two questions have been put to the manufacturer: whether a flush is required when moving from mineral ISO 100 to the NSF H1 grade, and under what contact conditions H1 is recommended for vacuum pumps in dairy processing. No published answer has been located, so none is stated here.
Only where a contact path exists between the pump and the product: an exhaust discharging over a line, a vacuum line meeting product or packaging, oil mist carry-over, or backstreaming. Where no contact path exists, mineral oil is the correct specification.
The food-grade grade is NSF H1 in ISO 100, the same viscosity grade, so it is a drop-in on grade. Whether the existing charge requires flushing has been put to the manufacturer and will be published when answered.
H1 certifies the lubricant formulation for incidental food contact. ISO 21469 audits the manufacturing and handling behind it.
Yes. Fuchs Cassida is Halal and Kosher certified. Certificates are available on request.
