Tempest VentMaster 365HD Fire Rescue Chainsaw

What is the Tempest VentMaster 365HD?

The VentMaster 365HD is a gas powered chainsaw Tempest builds for fire rescue cutting rather than for timber. It is sold in 2 configurations, and each one is a separate orderable part number. The chain pitch is 0.404 across all of them.

What is documented for this model, and what is not

Tempest prices the VentMaster 365HD in its 2026 book, and those rows are the whole of what is documented: the model, the bar length, whether a depth gauge is included and a 0.404 chain pitch. The 2025 Fire Catalog covers the 562 XP Mark II and 572HD saws and does not describe this model, so no engine output, cutting rate or material rating is stated here. Ask us and we will get it from Tempest in writing.

Which configuration should be ordered?

The bar length sets reach and the depth gauge sets how far the chain can bite, which is what stops a roof cut going through a truss or a ceiling below. A saw ordered without the depth gauge cannot be limited that way in the field. These are the configurations Tempest prices for this model:

• 16" with Chain, Depth Gauge: part number TV400-043
• 20" with Chain, Depth Gauge: part number TV400-044
