A paint sprayer includes an end bell, a motor connected to the end bell, a pump drive connected to the end bell, a pair of protrusions attached to an extending from the end bell such that each protrusion is cantilevered from the end bell, and a pump assembly comprising a pair of mounting holes and containing a piston. The pair of mounting holes is adapted to receive and slide onto the pair of protrusions to mount the pump assembly on the end bell as well as slide off of the pair of protrusions to remove the pump assembly from the end bell. The pump drive is configured to covert rotational motion output by the motor to reciprocal motion. The pump assembly is configured to pump paint when reciprocated by the pump drive while mounted on the end bell.

The invention relates to a method for coating an application surface (11) of a component (10), in particular of a building, within an application area (12) with a coating agent, in particular with a building paint, comprising a step of edge application to the application area (12) and a step of surface application to the application area (12), which does not include the edge application, characterised in that a first application method on the basis of the drop-on-demand method is used in the edge application step, and a second application method, which has a higher surface coating output than the first application method, is used in the surface application step.

An irrigation nozzle is provided with a grit diversion feature to divert grit away from the interior of the nozzle. The nozzle includes a pattern template that defines the irrigation pattern produced by the nozzle. The pattern template includes one or more flow channels that may be susceptible to clogging with grit. The grit diversion feature includes one or more grit vents to redirect grit away from the interior of the nozzle and may further include an inner wall about the central hub that helps protect the central hub from intrusion by grit.

The invention includes an air mover device used for fire mitigation and protection. The core component is an air mover unit whose discharge airstream can be positioned using air rudders to provide air flows in optimum directions and capacity to counter unwanted fire progression or to promote fires in cases of back-burns. Additional support components include a power supply, its fuel source, a speed control mechanism for the air mover, an air mover inlet protective screen, a sparger unit to impart suppressant or retardant into the airstream, and instrumentation and controls to ensure function and safety of equipment and personnel. This device can be on a static or mobile platform, towed or self-propelled and can be locally or remotely controlled.

A method for monitoring a nozzle mouthpiece for placing on a nozzle for spraying materials, in particular dispersions, emulsions or suspensions.
