Apparatus and associated methods relate to an airfoil configured to be disposed at a distal end of a tank. In an illustrative example, the airfoil may be configured such that, when the tank travels at a predetermined minimum speed in a proximal direction substantially parallel to a longitudinal axis of the tank, the airfoil coalesces off-coming air from the tank and distally repositions a low-pressure region downstream of the tank below a plane horizontal to the longitudinal axis. The region may be distally displaced, for example, by at least one of a length scale of the tank. A cross-section of the tank may, for example, define a substantially conic section. A span of the wing may, for example, be orthogonal to the longitudinal axis. The wing may, for example, be below an upper surface of the tank. Various embodiments may advantageously reduce turbulence in the wake of the tank.

The metal tank is divided internally into at least two compartments having respective wave-breaks, wherein each compartment comprises a pump system, a plurality of lines for recharging products, at least one quick-filling system for respective FO and ALR compartments, at least one manual traditional filling system, and the vehicle comprises at least one logical control system having at least one actuating panel, at least one actuating reel for the actuation of at least one hose, and at least one static mixer for the ALR/FO mixture having an overpressure safety system, wherein said safety system includes a recirculation system to the ALR compartment, a plurality of double-acting vent valves, at least one man access, at least one battery, a plurality of filters for the suction of recycled oils and at least two filters for direct supply to manufacturing equipment. The invention also relates to an associated process.

A vacuum unit includes a debris tank receiving wet or dry waste. A multi-cyclone separator is coupled to an outlet of the debris tank. The multi-cyclone separator receives the wet or dry waste from the debris tank and the multi-cyclone separator includes a plurality of cyclones. A filter is coupled to the outlet of the multi-cyclone separator and receives exhaust airflow from the multi-cyclone which then flows onto the blower or fan and is vented external to the vacuum unit.

Apparatus and installation methods for sampling ports are disclosed. Sampling ports include a port housing and a lid assembly. The lid assembly is configured to sealably close against the port housing. Additionally, the lid assembly can be secured, such as with a lock, to the port housing. In one aspect, the port housing includes a sample mount arrangement configured to receive a sampling assembly. The sample mount arrangement defines a sampling channel and the port housing defines a sampling opening and a first securing mount. The lid assembly includes a latch arrangement and defines a second securing mount.

A tank trailer may include a plurality of hoppers and a tension bar assembly extending between the hoppers.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a water tank supported by the chassis, an energy storage system coupled to the chassis and positioned rearward of the cab, a water pump supported by the chassis, and an electromagnetic device electrically coupled to the energy storage system. The electromagnetic device is coupled to the water pump and at least one of the front axle or the rear axle. The electromagnetic device is configured to receive stored energy from the energy storage system and provide a mechanical output to selectively drive the water pump and the at least one of the front axle or the rear axle.
