Glass Extension Tube for Fresh Roast Coffee Roasters | SR-540 & SR-800

• Boosts performance by improving bean movement and heat output
• Allows lower settings after the initial roast stage. Ideal for users with slightly inadequate supply voltage
• Complete kit with high-temp silicone bands and a double-lip seal
• Compatible with SR-540 and SR-800 roasters

This 10.25" tall glass extension tube is designed to dramatically improve performance, especially for the SR800. It enhances bean movement and provides better heat output, which is particularly useful for users with slightly inadequate power supply voltage.

The tube comes complete with high-temperature silicone bands (for the bottom) and a double-lip seal (for the midsection). It must be used in conjunction with your roaster's original chamber and chaff basket. Once the beans lighten in weight, this extension allows the machine to run on lower fan and heat settings—we typically recommend finishing on FAN 2 and HEAT 1.

Compatible with both the SR-540 and the SR-800 Fresh Roast Coffee Roasters (sold separately).

*The SR800 is designed to roast 8oz of green wet-processed coffee beans.  Going above the specified amount of green coffee can run the risk of plugging up the chaff basket and causing a chaff fire. The user must inspect and monitor the chaff basket for fullness and adjust the bean quantity as needed.  

*The SR540 is designed to roast 4oz of green wet-processed coffee beans.  Going above the specified amount of green coffee can run the risk of plugging up the chaff basket and causing a chaff fire. The user must inspect and monitor the chaff basket for fullness and adjust the bean quantity as needed.  

*Do not leave the roaster running while unattended.

*Stock glass roasting chamber not included.
