Essex manufactures and tests the complete assembly, which consists of the yoke and full column. Our unique design allows removing and replacing the control wheel in just minutes. The control wheel contains a force transducer as well as several single and multi-function switches for display cursor control, communications, pitch trim, auto-pilot disconnect, countermeasures, HUD declutter, and auxiliary functions.
The commercial derivative of the military C-130J Super Hercules is the LM-100J. Select design changes enables it to perform as a civil multi-purpose air freighter.
The 10 Liter LOX Ready to Install (RTI) system supplies oxygen to medevac patients. It provides a safe, compact and lightweight means of storing gaseous oxygen. The RTI consists of a 10 liter LOX converter with a heat exchanger and regulator mounted inside a sheet metal enclosure. This configuration allows installation of the equipment on the aircraft without the expense of a costly retrofit.
The 10 Liter LOX Converter within the RTI supplies up to 8,600 gaseous liters of oxygen at 70 psig. It is designed to MIL-DTL-19803 and tested to MIL-STD-810. The 10 Liter LOX RTI weighs approximately 50 pounds empty and 75 pounds when full. The enclosure mounts with four aircraft seat track fittings.

Hydraulic Pulsation Dampeners (or attenuators) are designed to reduce fluid pressure pulsations generated by aircraft hydraulic pumps. These pulsations can lead to system damage through check valve failure, tubing or hose rupture, loosened connections and cracked manifolds. In addition to the potential for system failure, hydraulic pressure pulsations can dramatically increase noise levels within the aircraft cabin. Unlike nitrogen-charged “muffler” devices, Essex hydraulic pulsation dampeners contain no moving parts and require no servicing. Constructed of high-strength 15-5PH hardened steel, these units are subjected to non-destructive tests prior to shipment.

The Essex PBE (Protective Breathing Equipment) is a portable, self-contained, personal smoke hood designed to safeguard flight attendants and cabin crewmembers from the effects of smoke, carbon dioxide, harmful gases and oxygen deficiency while managing in-flight fire, smoke or fume emergencies.
The PBE uses compressed aviator grade oxygen as its source of supply to crewmembers. The PBE smoke hood dons in only 15 seconds, with a unique design that eliminates the need for an oral/nasal mask. The amber-tinted hood provides 270° of visibility and the elastic neck seal requires no adjustment. The PBE provides 15 minutes of oxygen and one size fits most adults.
The Essex PBE (Protective Breathing Equipment) is a proven design that has been in service worldwide in commercial aviation fleets since 1989. This lightweight smoke hood is used by 90% of the commercial airline Industry in the United States, as well as many major international airlines.
System Design
The oxygen system in the Essex PBE (Protective Breathing Equipment) consists of two oxygen cylinder assemblies mounted to the bottom side of the neck seal. Special fabric and chemical panels inside the hood keep carbon dioxide concentrations at safe levels during the hood’s service period as the wearer exhales into the hood.
The Essex PBE features a battery-powered green and red light service/end-of-service Indicator. Mounted slightly below eye level on the left inner side of the hood, this light functions as a secondary indicator for monitoring oxygen activation, reassuring the wearer that the equipment is functioning.
The PBE smoke hood is folded and vacuum-sealed in a moisture resistant barrier pouch equipped with a replace by date label and an internal humidity indicator.
Essex Protective Breathing Equipment (PBE) requires very little stowage space and has the lightest stowage and end use weight. Several different stowage options are available.
The Essex PBE has the following approvals:

The Next Generation Portable Therapeutic Liquid Oxygen System (NPTLOX) is a low pressure portable 20.0 liter liquid oxygen storage and gaseous delivery system, capable of supplying up to 17,200 gaseous liters of oxygen at a maximum flow rate of 66 liters per minute at 50 psig. The unit features six quick disconnect outlet ports and comes with an accessory kit containing three 20 foot medical grade hoses, three flow control valves, three humidifier bottles, and three quick disconnect adapters. With six flow control valves attached, it can deliver oxygen to six patients at flow rates from .5 to 15 liters per minute. The quick disconnect outlet ports can also supply 50 psi of oxygen to other medical devices or to oxygen regulators for additional patients. The NPTLOX has been successfully tested to work in tandem with commonly used ventilators. Weighing 155 pounds when full, the NPTLOX can be carried by two ground support personnel using the four-position locking handles. It can also be mounted in an aircraft. The NPTLOX requires no external power and uses just two 9-Volt batteries for the quantity indicator. The system has been tested to MIL-STD-810.
