Bio-Ultimax™ 1500 Full Synthetic Dielectric Hydraulic Fluid (Altec Approved, Biodegradable, EPA VGP)

Full synthetic dielectric hydraulic fluid designed for aerial lift, bucket truck, and utility equipment applications, delivering high dielectric strength (>35 kV) and meeting Altec bucket truck approval requirements for electrical insulating performance in demanding environments. Engineered for hydraulic systems where electrical safety is critical, it provides reliable operation across mobile and stationary equipment.

Designed to replace conventional petroleum-based and synthetic hydraulic oils, Bio-Ultimax™ 1500 delivers excellent anti-wear (AW) performance, oxidation stability, rust protection, and demulsibility in vane, piston, and gear pump systems. Its advanced formulation is highly resistant to moisture and corrosion in both fresh and saltwater environments, passing ASTM D-665 A and B rust tests for long-term protection.

Formulated with high viscosity index base stocks that exceed traditional synthetic performance, this fluid provides consistent operation across a wide temperature range while improving energy efficiency and equipment life. The zinc-free additive system delivers environmentally responsible performance while meeting demanding hydraulic system requirements and EPA VGP standards for environmentally acceptable lubricants (EALs).
