HVAC Control Gear Oil

This gear oil serves HVAC systems and other industrial equipment that require a food-grade synthetic lubricant. It meets NSF H1 standards for incidental contact in processing environments. Maintenance teams select it where cleanliness and regulatory compliance are essential.

Thermal Performance

The fluid operates from 15 degrees F to 180 degrees F with a flash point of 268 degrees F and a pour point of -43 degrees F. ISO 150 viscosity and 90W SAE grade maintain film strength across that range. Timken OK load of 40 lb indicates load-carrying capacity under pressure.

NSF H1 Certification Benefit

NSF registration 152879 confirms H1 food-grade status so the lubricant can be used where incidental food contact may occur. Synthetic base oil with no additives reduces contamination risk. Yellow colour aids visual identification during inspection and top-up.

Highlights

  • Food-grade NSF H1 certification for safe incidental contact
  • Synthetic base oil with no additives runs clean from 15 °F to 180 °F
  • 150 ISO / 90W SAE viscosity matches heavy-duty gear specs

Questions about this item

How do I correctly fill the gearbox with this 150 ISO 90W SAE synthetic gear oil?

Drain the old lubricant completely, then refill with the yellow H1 food-grade oil until the gearbox reaches its specified level — the step most often missed is running the equipment briefly and re-checking the level afterward.

When will this NSF H1 synthetic gear oil need to be replaced?

Replace it when the lubricant darkens, shows contamination, or reaches the service interval set by the equipment manufacturer; the oil itself carries no additives that deplete on a fixed schedule.

At what temperature does this 90W gear oil hit its upper operating limit?

The maximum continuous operating temperature is 180 degrees F; sustained use above that point accelerates oxidation and shortens fluid life.
