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.
