An air intake scoop intended to be fastened on a panel of an aircraft includes an air inlet mouth having a wall, a peripheral collar intended to be fastened to the panel, and a bearing element intended to support the air circulation duct. The air inlet mouth is made of a thermoplastic material and the bearing element is fastened on the peripheral collar so as to achieve a pressure barrier in case of breakage of the wall of the air inlet mouth.

A vented roof panel is provided for an overhead portion of a roll-over protection system of an off-road vehicle. The vented roof panel comprises a planar member that includes a shape and a curvature that match the overhead portion to enable closely attaching the vented roof panel to the roll-over protection system. The planar member is formed of any of various plastics, such as injection molded plastic, or other similar materials. An air scoop including an air inlet port is centrally disposed in the planar member. The air inlet port is disposed in a forward-facing portion of the air scoop and configured to direct an airstream from outside to underneath the vented roof panel. The vented roof panel may be attached to tubular frame members comprising the roll-over protection system by way of one or more suitable fasteners.

An air vent for a vehicle or vehicle canopy includes an external and an internal duct. The external duct has an inlet and an outlet. The height of the outlet is less than that of the inlet. The inlet and the outlet are arranged such that, in use, an uppermost point of the inlet is located above an uppermost point of the outlet. The internal duct is in fluid communication with the external duct via one or more openings arranged in the internal duct or at a junction between the internal duct and the external duct. The internal duct is configured to be in fluid communication with an interior of the vehicle via a slot defined by the vehicle. The or each opening is arranged such that, in use, the uppermost point of the outlet of the external duct is located below a lowermost point of the or each opening.

A ventilator for exhausting gas from an exhaust port, by utilizing wind or relative wind around and through the ventilator to create a reduced pressure zone at an open exhaust port. Tapered intermediate portions extend from the opposite ends of a centrally located throat portion within a body of the ventilator to a pair of opposite mouths through which gas can flow out through the ventilator from the exhaust port. Each mouth of the ventilator has an opening with an area significantly larger than the area of a flow path within the throat portion. The throat portion may be of constant internal cross-sectional area over its entire length.

A fresh air intake system for overburden drills with an air intake assembly mounted along the drill mast to access air at the greatest practical height above ground, an air filter assembly, and a pressure blower/circulating fan assembly to supply the cleanest air practicable into the operator's cab under positive pressure. The height of the drill mast is utilized to access cleaner air at greater heights, with the air inlet located strategically toward the top of the mast. The intake assembly includes a rain cap, an intake tube mounted along the drill mast, and a flexible section at the drill mast pivot point to accommodate raising and lowering of the mast without interference or obstruction. The air filter assembly is mounted in series with the pressure blower/circulating fan assembly, which operates with negative inlet pressure and supplies filtered air under positive pressure into the enclosed cab.
