Recommendations

  • It is recommended that a Leister brand blower be used to supply this tool with air
  • Minimum air flow requirements must be adhered to, failure to do so may result in damage to the tool
  • For help choosing the correct heater and blower combination please contact your sales representative

Why Buy From Us

The LHS 21 Air Heater is available in Canada only through STANMECH and its distributor network. Tools bought through us are electrically certified for use in Canada. In many cases this entails replacing cords or switches in the tool to meet stringent CSA standards. Each tool is physically inspected by an approved field inspector prior to certification. We service everything we sell from our facility in Burlington, Ontario, Canada.
