An improved apparatus and method for pulse-jet cleaning of filter bags in a baghouse using pulsed, high-pressure/low-volume, intermediate-pressure/intermediate-volume, or low-pressure/high-volume pulsed air flow. Relative movement between a first tubular member and a second member causes apertures in the members to align intermittently. When the apertures are aligned, pressurized air is fed, through a pulse valve or from a combustion chamber, into the tubular first member and flows out of the aligned apertures in a short, energetic pulse. The pulse is directed down into a filter bag arranged below the pulse pipe to pulse-clean the filter bag or into another pulse pipe arranged above a filter bag.
