Low-Pressure Vacuum Furnace VFL Series｜Space-Saving Design & 50% Gas Reduction

The VFL Series Low-Pressure Vacuum Furnace offers efficient heat treatment for steel components with a compact design, square vacuum chamber, and reduced gas usage by about 50%.

The VFL Series Low-Pressure Vacuum Furnace is engineered for hardening, brazing, and melting of materials such as tool steel, alloy steel, and stainless steel. Featuring a square vacuum chamber, the system optimizes internal space while cutting gas consumption by approximately half compared to traditional vacuum furnaces.

Its compact structure also reduces installation area by about 50%, making it ideal for factories with limited floor space. The use of graphite insulation prevents moisture absorption, reducing the risk of oxidation—especially important for sensitive materials like SUS (stainless steel).

Equipped with an RC fan for uniform heat distribution and an inverter-controlled cooling fan, the furnace supports energy-efficient, precise thermal processing.
