What This Means for Aviation Operations
The BOSS Air System is ideal for spot cooling or heating in aircraft cabins, avionics bays, small compartments, or maintenance work areas without powering engines or auxiliary systems. Its compact, mobile design and low amperage draw make it easy to deploy where temperature control is needed most during ground handling or hangar maintenance.

QUESTIONS & ANSWERS
Yes! The Start Pac BOSS is designed to operate on 208V to 240V RMS, single-phase power and requires only 20A service, making it a practical option for many hangar and facility setups. It also includes an integral breaker/switch for straightforward operation.
Yes. The Start Pac BOSS includes a 50′ input power cable, allowing flexible placement around aircraft during ground operations. Longer cable lengths are available upon request at the time of ordering, ideal for when power access is farther away in larger hangars or ramp areas.
The Start Pac BOSS typically draws about 20.8 amps during operation. This efficient power requirement is a key reason many teams use it for portable aircraft cooling or heating without needing specialized electrical infrastructure.
It can provide both! The BOSS operates in cooling or heating mode, allowing crews to use the same mobile HVAC unit year-round depending on conditions.
The Start Pac BOSS delivers approximately 24,000 BTU of cooling and 24,000 BTU of heating (optional) through its heat pump design. This makes it useful for maintaining more stable temperatures during aircraft maintenance and ground operations.
Yes! The Start Pac BOSS Air System comes standard with a 16′ air delivery hose that’s 12″ in diameter. The unit uses patent-pending retractable ducting that stores neatly in an integrated onboard compartment, helping keep the hose protected and reducing clutter in hangar or ramp environments.
The unit has a maximum sound level of 76 dB (76 dBA). This helps keep noise manageable when the BOSS is operating near technicians, aircraft, and other ground support equipment.
The Start Pac BOSS is self-draining, so a separate drain kit is not required. During operation, the included drainage tube removes approximately 5.2 pints of moisture per hour. Operators can either collect drainage in a bucket or route it through additional tubing to a more convenient drain location.
The Start Pac BOSS includes a standard drain tube, and longer factory drain tube options may be limited. If additional reach is needed, most teams simply attach compatible tubing or hose sourced locally to extend the drainage line and route moisture to a bucket or drain point that fits their work area setup.
Yes! The unit includes a replaceable air filter, allowing teams to perform basic upkeep as needed based on use conditions. Keeping the filter maintained can help support airflow and consistent HVAC performance over time.
The Start Pac BOSS uses R32 refrigerant with a charge of 47.3 oz. This sealed refrigerant system supports reliable performance while helping reduce routine maintenance requirements.
The Start Pac BOSS is rated IP24 for moisture protection, providing splash resistance in real-world operating environments. It’s still best practice to follow standard ground equipment handling procedures when working in wet conditions.
The Start Pac BOSS weighs 463 lbs (210 kg) and is built as a mobile unit for repositioning around the aircraft as needed. It also features four solid wheels for improved mobility and stability.
Yes! The Start Pac BOSS Air System is listed as made in the USA, which can be helpful for organizations that prioritize domestic manufacturing or sourcing requirements.
