Mantis ComposT-Twin Features
Twin Composter Doors and Frame

The ComposT-Twin (4000-00-03) dual-bin composter by Mantis has removable, twin-latch doors for easy loading and unloading of materials. The steel frame holds the composter 32″ off the ground.
- Add on the Sifter Screen (shown above) for easier separation of fine compost particles.
Composter Ventilation and Drainage

Aeration and drainage units are found on the drums and doors. These vented doors let oxygen enter the composter and allows excess moisture to drain. Vented end caps on the drums assure proper airflow and moisture control.
Mixing and Turning in the Composter

ComposT-Twin makes a constant supply of compost. 25-cubic foot capacity in each bin! Built-in mixing fins mix materials as the compost tumbler is rotated. Keeps contents from sticking to sides of compost drum. Turn both drums simultaneously with the crank handle and gear mechanism.
